Description

  The present invention relates to a computer capable of processing a calculation that handles a remainder.

  When division (dividend / divisor) is performed by a general computer, the solution (quotient) is displayed as an integer when divisible, and as a decimal when not divisible. When the solution of division is expressed only by an integer (integer quotient), the solution is expressed by using a fraction as a remainder (too much), but the remainder is not displayed on a general computer. Therefore, calculators having a surplus display function (for example, Casio Computer Co., Ltd., model number: AZ-60F, etc.) are sold as educational computers, and related technologies are disclosed (for example, patent documents). 1). In addition, a technique for displaying a remainder is also disclosed (see, for example, Patent Document 2).

  In pharmacies, when counting and dispensing pharmaceuticals such as PTP (press through pack) -packed tablets and capsules, heat-packed powders, etc., there are often scenes where division that cannot be divided is performed and the remainder is used again. . For example, it is assumed that a certain medicine X (heat packaging) contains 42 packages (14 sets of 3 consecutive packages) in one box. Assume that this medicine is prescribed 100 packs by a doctor. Unlike over-the-counter drugs, pharmacies must accurately prescribe the number of medicines prescribed by the doctor, but the number prescribed depends on the age and symptoms of the patient, the dosage of the drug, etc. You need to check the prescription and calculate the number. Therefore, in order to produce 100 packets, when a calculation is performed using a general calculator (with decimal display), the following three procedures are taken.

  First, 100 ÷ 42 is calculated to obtain the necessary number of boxes, and 2.38095... Is obtained as a quotient. As a result, it is understood that two boxes are insufficient, but three boxes are too many. Next, 100-42 × 2 is calculated, and 16 is obtained as the shortage when two boxes are prepared. Further, 16 ÷ 3 is calculated to obtain the required number of triplets, and 5.33333. This shows that 5 sets are insufficient, but 6 sets are too much. Next, 16−3 × 5 = 16−15 is calculated to obtain the individual number of packages, and 1 is obtained. As a result of the above calculation, it can be seen that in order to prepare 100 packets, it is only necessary to prepare 2 packages, 5 consecutive packages and 5 individual packages.

  In addition, when actually making 100 packages, it is possible to calculate by subtracting from one box more than the above-described stacked calculation in consideration of the calculation speed and the inventory quantity. In this case, the following calculation is performed. First, 100 ÷ 42 is calculated, and 2.38095... Is obtained as a quotient. At this time, the quotient is incremented by 1 and 3 boxes are prepared, and the total number of packages contained in the 3 boxes is calculated as 42 × 3 = 126. Next, in order to obtain an extra number contained in the three boxes prepared, 126−100 = 26 is calculated, and it is understood that the desired 100 packets can be obtained by preparing three boxes and removing 26 packets therefrom.

  As described above, there is a problem in that there is no means for processing simply and accurately in spite of the fact that, in calculations at pharmacies, etc., the remainder is calculated and reused frequently and the accuracy is required. . Therefore, an object of the present invention is to provide a computer capable of processing a calculation that handles a residue simply and accurately.

Further, the display unit may display the result of the first calculation as an equation including the first quotient C ₁ and the first remainder D ₁ or as an equation including the second quotient E ₁ and the second remainder F _1. Specifically, the computer may display the result of the first calculation in the format of A ₁ = B ₁ × C ₁ + D ₁ or in the format of A ₁ = B ₁ × E ₁ + (F ₁ ). With such a configuration, the meaning of the calculation result can be displayed in an easily understandable manner.

With such a configuration, it is possible to quickly perform an operation that reuses the remainder.

In the present invention, the display unit may display the result of the first calculation as an equation including the first quotient C ₁ and the first remainder D ₁ . Specifically, the computer may display the result of the first calculation in the format of A ₁ = B ₁ × C ₁ + D ₁ . With such a configuration, the meaning of the calculation result can be displayed in an easily understandable manner.

In another aspect of the computer according to the present invention, the computer includes a dividend A ₁ that is a number greater than or equal to 0 and n (n is an integer greater than or equal to 2) divisors (B ₁ , B ₂ ,..., B _n (where For an integer k from 2 to n, an input unit for inputting a divisor group B _G that is a set of B _k−1 > B _k )), and an input dividend A ₁ and divisor group B _G The dividend A ₁ is a set of _n quotients (C ₁ , C ₂ ,..., C _n ) that can be expressed as B ₁ × C ₁ + B ₂ × C ₂ +... + B _n × C _n + D _n. An arithmetic processing unit that calculates a certain quotient group C _G and a remainder D _n , n number of quotients (C ₁ , C ₂ ,..., C _n ) belonging to the quotient group C _G calculated by the arithmetic processing unit and a remainder and a display unit for displaying the D _n.

In the present invention, the input unit, the divisor group B _G may be input configured to be able to collectively. For example, the input unit includes a preset key assigned a predetermined divisor group B _G, may allow input collectively divisor group B _G by an input operation to the preset key.

In the present invention, the display unit includes n integral quotient which constitutes the integral quotient group C _G, may be distinguishably displayed visually and the remainder D _n. For example, the display unit is different delimiter and displays separated by n pieces of integral quotient a predetermined delimiter constituting the integral quotient group C _G, and integral quotient group C _G and a remainder D _n to a predetermined delimiter They may be displayed separated by symbols. Here, the “separator” is a character (or character string) other than a number, a decimal point, and an operator, and may include a space.

[First Embodiment]
Hereinafter, a case where the computer according to the first embodiment of the present invention is used for calculating a medicine dispensing quantity and an order quantity in a pharmacy will be described as an example with reference to the drawings. FIG. 1 is a configuration diagram showing an outline of a computer 100 according to the first embodiment of the present invention. FIG. 2 is a functional block diagram of the computer with remainder display 100 according to the first embodiment of the present invention. As shown in FIG. 1, the computer 100 is configured by arranging a display unit 120 such as a liquid crystal panel and an input unit 130 including various input keys in a casing 110. The input unit 130 includes a numeric input key 131, four arithmetic keys 132, a remainder calculation key 133, a remainder use key 134, a remainder storage key 135, an answer key 136, a display switching key 137, a clear key 138-1, and an all clear key 138-. 2 and an order quantity key 139. Further, the computer 100 includes an arithmetic processing unit 140 such as a CPU and a storage unit 150 inside the housing 110. The storage unit 150 includes, for example, a ROM that stores a program executed by the arithmetic processing unit, and a RAM that stores input numbers, calculation results, and the like.

  The display unit 120 displays input numbers, operators, calculation results, and the like. Each key constituting the input unit 130 is configured by a push button switch, for example. Hereinafter, functions assigned to the functions of the keys will be described.

  The numerical value input key 131 is a key for inputting a numerical value, and includes numbers from 0 to 9, and may further include a decimal point. Furthermore, when there is a frequently used number (for example, in the case of a pharmacy, the number of prescriptions is often specified by the designation such as weekly or after three meals, so frequently use 14, 21, 30, etc.), etc., enter the number. A key may be provided. The four arithmetic operation keys 132 are used for addition, subtraction, division, or multiplication of a first input value input immediately before the key is pressed and a second input value input immediately after the key is pressed. This is a key to instruct calculation.

  The remainder calculation key 133 is a key for instructing an operation (hereinafter referred to as a remainder calculation) for obtaining an integer and a remainder as a result of division. The remainder use key 134 is a key for using the remainder obtained by the previous division as the first input value in the next calculation. When the remainder in the previous division is 0, 0 is set as the first input value in the next calculation. Note that the quotient of the immediately preceding division may be used as the first input value in the next calculation instead of the remainder (or selectively with the remainder). For this purpose, a quotient use key is further provided. May be. The remainder storage key 135 is a key for temporarily storing the remainder in the storage unit 150. The stored remainder may be called by pressing the remainder storage key 135 again, or a call-only key (not shown) may be provided and called when the call-only key is pressed. The remainder storage key 135 is effective when the remainder is not used immediately after division but is desired to be utilized after some other calculation. In addition to the remainder storage key 135, a quotient storage key for storing the quotient of the previous division in the storage unit 150 may be further provided.

  The answer key 136 instructs the completion of the input of the second input value (or the final input value if it is allowed to input an operator / numerical value after the second input value in operations other than the remainder operation). This is a key for causing the arithmetic processing unit 140 to execute arithmetic operations based on the inputs up to and displaying the calculation results on the display unit 120. The display switching key 137 is a key for switching the expression format of the calculation result displayed on the display unit 120 by pressing the answer key 136. The expression format switched by operating the display switching key 137 will be described later. The clear key 138-1 is a key for erasing the value or operator input immediately before from the storage unit 150. The all clear key 138-2 is a key for erasing all information stored in the storage unit 150 regarding a series of inputs and calculation results as well as the value and operator input immediately before.

  The order quantity key 139 is a key for obtaining an order quantity of medicines procured in a box unit or the like. If the prescribed medicine is not in stock, the pharmacy may urgently arrange to deliver the necessary amount of medicine X to the wholesaler as quickly as possible. At this time, the order unit handled by the wholesaler varies depending on the type of medicine. In order to accurately and quickly determine how many order units the order quantity should be, when the order quantity key 139 is pressed, the computer 100 determines the minimum order quantity based on the input procurement quantity and order unit. Ask for. Specifically, the arithmetic processing unit 140 of the computer 100 divides the procurement quantity input as the first input value by the order unit input as the second input value after pressing the order quantity key 139, and calculates the decimal number. The numerical value rounded up to the first place is the calculation result.

  The key arrangement shown in FIG. 1 is merely an example, and is not limited to the arrangement shown in FIG. 1 as long as a similar function can be realized.

  Here, using the computer according to the present embodiment, the dividend for the first division is 100, the divisor is 42, and the second division (division with the first division remainder as the divisor) is 3. An example of a procedure for performing the above will be described. This calculation is based on the situation where 100 medicines are to be prescribed, and if the medicine is in stock in the form of a 42-pack box and a triple-pack, how many boxes, triple-packs, and individual packs are prepared. This corresponds to the calculation for determining what should be done. Prior to starting the calculation, the all clear key 138-2 is pressed to delete the past input contents and calculation results from the storage unit 150. Subsequently, the numerical input key 131 is used to press 1, 0, 0 to input 100 as the first input value, and then the remainder calculation key 133 is pressed to instruct the remainder calculation. Subsequently, the numerical input key 131 is used to press 4, 2 to input 42 as the second input value, and the answer key 136 is pressed to obtain the calculation result. The first input value, the second input value, and the calculation instruction input by pressing the remainder calculation key 133 by pressing the numeric input key 131 are stored in the storage unit 150 and displayed on the display unit 120. Is done. Further, when the answer key 136 is pressed, an operation based on the input is executed, and an integer quotient (hereinafter referred to as a first integer quotient) whose product with the divisor becomes the maximum when the dividend is less than or equal to the dividend, and the divisor and the first integer from the dividend. The remainder obtained by subtracting the product with the quotient (hereinafter referred to as the first remainder) is required. The calculation result is stored in the storage unit 150 and displayed on the display unit 120. In this example, “2... 16” is displayed on the display unit 120. As described above, the calculation result display method may display the quotient and the remainder at the same time, or by pressing a predetermined key such as the display switch key 137 while individually displaying the quotient and the remainder. The display may be switched.

  Next, the surplus use key 134 is pressed. Then, 16 that is a remainder in the first division is input as the first input value in the next calculation and displayed on the display unit 120. Subsequently, the remainder calculation key 133 is pressed to instruct the remainder calculation. Subsequently, the numerical value input key 131 is used to press 3, and the answer key 136 is pressed to obtain a calculation result. “5... 1” is displayed on the display unit 120 as the calculation result.

  In the computer 100 of this embodiment, the calculation result may be expressed not only by a quotient and a remainder but also by an expression. For example, the result of the first division in the above calculation example may be displayed as 100 = 42 × 2 + 16, and the result of the second division may be displayed as 16 = 3 × 5 + 1. In order to be able to select the expression method of the calculation result, the display switching key 137 may be pressed to switch between the expression in the quotient / residue and the expression in the mathematical expression.

  When the computer 100 according to the present embodiment repeats division while reusing the remainder, the calculation result may be accumulated and displayed as a series of calculation results. The meaning of the calculation result of the two divisions in the above example is that when preparing 100 medicines, prepare 2 boxes of 42 packages, 5 triple packages, and 1 individual package. It means that it should be. As a display of the calculation result, it is preferable to display the quotient and remainder of the first division and the quotient and remainder of the second division in order, such as “2... 16, 5. In addition, when the display by the expression is selected by the display switching key 137, the calculation result may be displayed as “100 = 42 × 2 + 3 × 5 + 1”. Similarly, when the third and subsequent divisions are repeated, the calculation result may be displayed by an expression using a quotient / remainder or an expression.

  As another display example, when division is repeated n times, the quotient and remainder may be displayed only for the last one division, and only the quotient may be displayed for the first to (n-1) th operations. . In this case, the display unit 120 preferably displays the n quotients and the remainder so as to be visually distinguishable. For example, the display unit 120 may display the n quotients separated by a predetermined delimiter and the remainder divided by a delimiter different from the quotient. Here, the delimiter may be a character (or character string) other than a number, a decimal point, and an operator, or a space (space). Specifically, n quotients and 1 divide quotient, 2nd divide quotient,..., Nth divide quotient, nth divide remainder, etc. It is recommended to display the remainder by separating it with a space or the like. Or, n quotients are displayed in parentheses, as in {{quotient of the first division, quotient of the second division,..., Quotient of the nth division}. At the same time, the remainder of the nth division may be displayed outside the parentheses. In the above example, curly brackets (curly brackets) are used, but parentheses (round brackets), square brackets (square brackets), braces, etc. may be used. Such display makes it possible to distinguish the quotient from the final remainder (the remainder of the nth division) and to save the number of display digits. As another example of visually distinguishable display, the n quotients and the remainder may be displayed in different formats (for example, font, character size, color, thickness, italics, presence of underline, etc.). Alternatively, it may be visually distinguishable by a dynamic change such as blinking one of the quotient group and the remainder.

  The computer 100 may determine the upper limit of the number of continuous calculations to be displayed as a series of calculation results in consideration of the constraints such as the size of the display area of the display unit 120 and the storage capacity of the storage unit 150. When all clear key 138-2 is pressed, when repetition of division for reusing the remainder is interrupted, when the upper limit of the number of consecutive calculations is reached, etc., it is configured not to display a series of calculation results. May be. Further, by pressing the display switching key 137 a predetermined number of times, it is possible to select a display as a series of calculation results and a display in another expression.

As described in the problem of the present invention, when a predetermined number is actually made, there is a subtraction type calculation method instead of the addition type calculation method as described above. In other words, when there is a remainder in the division, the excess number is subtracted from the product of the number obtained by adding 1 to the first quotient (hereinafter referred to as the second quotient) and the divisor of the division. The remainder when the second quotient is adopted (hereinafter referred to as the second remainder) corresponds to the value obtained by subtracting the product of the divisor and the second quotient from the dividend, and this value should be subtracted because it is a negative value. You can know the number. Note that the operation for obtaining the second remainder can be simplified to the operation of subtracting the divisor from the first remainder. Applying the subtraction type calculation method to this example results in the following calculation.
100 = (42 × 3) + (16−42) = 42 × 3 + (− 26)
This means that when 100 medicines are prepared, three 42-pack boxes are prepared, and 26 packs are extracted from the one box.

  When the subtraction type calculation result is displayed on the display unit 120 in the above calculation example, the second remainder may be displayed as a negative number, such as “3. Further, when displaying as a mathematical expression, it is preferable to display “100 = 42 × 3-26” or “100 = 42 × 3 + (− 26)”.

  In an actual use situation, whether the addition type calculation result or the subtraction type calculation result is appropriate differs depending on the situation. Therefore, the computer 100 may be configured to check both calculation results. . For example, by pressing the display switching key 137, the display can be switched between (42 × 2) +16 which is the addition type calculation result and (42 × 3) −26 which is the subtraction type calculation result. Configure. Specifically, the expression of the quotient / remainder and the expression of the mathematical formula may be combined with the calculation results of the addition type and the subtraction type to switch the four types of expression. You may provide the key which switches the display of an addition type and a subtraction type separately from the key which switches the expression by a quotient and remainder, and the expression by an expression. Alternatively, the addition type calculation result (that is, the first quotient and the first remainder) and the subtraction type calculation result (that is, the second quotient and the second remainder) are displayed on the display unit 120 at the same time. Also good.

  Note that a key for obtaining a subtraction type calculation result may be provided separately from the remainder calculation key 133. Further, for example, when the remainder calculation key 133 is pressed an odd number of times, an addition type calculation result (that is, the first quotient and the first remainder) is obtained, and when the remainder calculation key 133 is pressed an even number of times, a subtraction type calculation result (that is, the second calculation result) For example, an addition type calculation result and a subtraction type calculation result may be selected in accordance with the number of times the key is pressed. Alternatively, the user may set whether to obtain an addition type calculation result or a subtraction type calculation result when the remainder calculation key 133 is pressed. Even in the form described in this paragraph, switching between addition type and subtraction type display, and switching between expression based on quotient / remainder and expression based on expression may be executed as described above.

  When the remainder of the previous division is used as the first input value for the next calculation using the remainder use key 134, the remainder to be used is not only the first remainder but also the second remainder which is a negative value. Good. In this case, it may be configured to be able to select which one to use. The remainder used by the remainder use key 134 is used as a first input value for normal four arithmetic operations (addition / subtraction / multiplication / division) and remainder calculation (including the above-described subtraction type calculation). As an example of using a negative value as the first input value in the subtraction type remainder calculation, when performing a remainder calculation of −26 ÷ 3, the quotient is −8, the remainder is −2, and the calculation result is “−8 ...- 2 "or" -8 too much-2 "or the like may be displayed on the display unit 120. When displaying the calculation result as an expression, for example, “−26 = 3 × (−8) −2” or “−26 = 3 × (−8) + (− 2)” may be displayed. Note that the parentheses surrounding the quotient when displayed as an expression may be omitted for convenience of display.

  When the computer 100 has a function of displaying the quotient of n divisions and the remainder of the last one division as a series of calculation results for the above-described division repeated n times, the series of calculations includes a subtraction type calculation. In such a case, such a display may not be possible, or a series of calculation results up to the subtraction type calculation may be displayed with the subtraction type calculation as the last (that is, the nth) operation. Further, after a subtraction type calculation, a predetermined number of divisions (for example, one time) may be allowed, and a series of calculation results up to a predetermined number of times after the subtraction type calculation is performed may be obtained. In addition, when a subtraction type calculation is included, a series of calculation results may be displayed without any limitation. Note that the computer 100 may determine an upper limit of the number of consecutive calculations to be displayed as a series of calculation results in consideration of constraints such as the size of the display area of the display unit 120 and the storage capacity of the storage unit 150.

[Second Embodiment]
Hereinafter, a computer according to a second embodiment of the present invention will be described with reference to the drawings. The feature of the computer 200 according to the present embodiment is that a combination of n divisors is used when n divisions are repeated instead of specifying a divisor for each division when the division is further repeated using the remainder of division. This is different from the first embodiment in that divisor groups that are Since it is the same as that of 1st Embodiment except the point provided with the structure for implement | achieving designation | designated of such a divisor group, description here is abbreviate | omitted.

  FIG. 3 is a block diagram showing an outline of a computer with a remainder display according to the second embodiment of the present invention. FIG. 4 is a functional block diagram of a computer with a remainder display according to the second embodiment of the present invention. As shown in FIG. 3, the computer 200 includes a divisor group designation start key 201, a next divisor designation key 202, a divisor group designation end key 203, and a divisor group preset key, in addition to various keys provided in the computer 100 of the first embodiment. 204 and a preset registration key 205. The computer 200 according to the present embodiment uses the divisors included in the divisor group specified by these keys to further repeat division using the remainder of division and displays the result. The n divisors constituting the divisor group are designated in descending order, and are the first divisor, the second divisor,. Note that it is possible to specify the n divisors in a random order rather than in the descending order, and after the divisor group has been input, the divisors may be rearranged in the descending order and used for the calculation.

  The divisor group designation start key 201 is a key for designating designation of a divisor used in a remainder calculation designated by pressing the remainder calculation key 133 as a divisor group. After pressing the divisor group designation start key 201, the first divisor is input using the numerical value input key 131. The next divisor designation key 202 is a key for confirming the divisor being input and instructing to start inputting the next divisor. The divisor group designation end key 203 is a key for confirming the divisor being input and instructing that the divisor being input is the last divisor in the divisor group.

  The divisor group preset key 204 is a key for calling a divisor group registered in advance, and is frequently used without requiring the operations of the divisor group designation start key 201, the next divisor designation key 202, and the divisor group designation end key 203. The divisor group can be input by a single operation. The preset registration key 205 is a key for instructing registration of a divisor group to be assigned to the divisor group preset key 204. For example, a divisor group designated immediately before or after the preset registration key 205 is pressed is a divisor group preset key. 204. The divisor group to be registered is input using a divisor group designation start key 201, a next divisor designation key 202, a divisor group designation end key 203, and a numerical value input key 131. The divisor group assigned to the divisor group preset key 204 is stored in the storage unit 150 and is updated by a preset registration operation. Note that a plurality of divisor groups may be registered. In this case, when the divisor group preset key 204 is provided as many as the number of divisor groups that can be registered, or designated by an operation sequence of the divisor group preset key 204 or other keys, a desired divisor group can be called. Good.

  Next, an example of an operation method for obtaining a result of an operation that repeats division of a remainder (hereinafter referred to as a batch remainder operation) by specifying a divisor group using the computer 200 will be described. Here, as an example, in a situation where 270 pills should be prescribed (for example, 3 pills per day, 90 days of batch prescription), the drug is 189 wraps in a large package, 42 wraps in a middle wrap, 21 wraps An example of calculation for obtaining a small package and a method for preparing a 270 package when an individual package can be prepared will be described.

  Prior to starting the calculation, the all clear key 138-2 is pressed to delete the past input contents and calculation results from the storage unit 150. Subsequently, 270 is input as the first input value (dividend) by pressing 2, 7, 0 using the numeric input key 131, and then the remainder calculation key 133 is pressed to instruct the remainder calculation. Subsequently, the divisor group designation start key 201 is pressed to instruct to input the divisor group in the batch remainder calculation. Next, the numerical input key 131 is used to press 1, 8, and 9 to input 189 as the first divisor in the divisor group. Subsequently, when the next divisor designation key 202 is pressed, 189 is determined as the first divisor and the second divisor can be input. Then, 42 is input as the second divisor with the numerical value input key 131. Subsequently, when the next divisor designation key 202 is pressed, 42 is determined as the second divisor, and the third divisor can be input. Then, 21 is input as the third divisor using the numerical value input key 131, and the divisor group designation end key 203 is pressed to end the divisor group input. As the divisors belonging to the divisor group, three numerical values 189, 42, and 21 are input. Further, when the answer key 136 is pressed, the first division of the dividend 270 and the first divisor 189, the second division of the first division 81 and the second divisor 42, A third division of 39 which is the remainder of the second division and 21 which is the third divisor is executed.

  The calculation result is stored in the storage unit 150 and displayed on the display unit 120. When a divisor group by n divisors is designated, the calculation result may display the n quotients (hereinafter referred to as the quotient group) for the 1st to nth divisions and the remainder of the nth division. It is preferable that the display unit 120 displays the n quotients and one remainder constituting the set quotient group so as to be visually distinguishable. For example, the display unit 120 may display the n quotients separated by a predetermined delimiter, and the set quotient group and the remainder may be displayed separated by a delimiter different from that for dividing the quotient. Here, the delimiter may be a character (or character string) other than a number, a decimal point, and an operator, or a space (space). Specific examples include n quotients and 1 divide quotient, 2nd quotient quotient,..., N divide quotient, and n divide remainder. Display the remainder separated by a space. Or, n quotients are displayed in parentheses, as in {{quotient of the first division, quotient of the second division,..., Quotient of the nth division}. At the same time, the remainder of the nth division may be displayed outside the parentheses. In the above example, curly brackets (curly brackets) are used, but parentheses (round brackets), square brackets (square brackets), braces, etc. may be used. In the case of the above calculation example, the calculation result is displayed as “{1, 1, 1} 18”, for example. Another example of a visually distinguishable display is that n quotients and remainders are displayed in different formats (font, character size, color, thickness, italic, underlined characters, etc.) Good. Alternatively, it may be visually distinguishable by a dynamic change such as blinking one of the quotient group and the remainder. Further, not only the quotient in the calculation result but also when the divisor group is input, n values may be enclosed in parentheses and separated by a delimiter. In this case, it is assumed that symbols such as parentheses indicating that n values constitute a divisor group and symbols such as parentheses indicating that n values constitute an integer group use the same thing. In order to distinguish the two, different ones may be used.

  The calculation result may be displayed using a mathematical formula. For example, in the case of the above calculation example, “270 = 189 × 1 + 42 × 1 + 21 × 1 + 18” may be displayed on the display unit 120 as the calculation result. According to the expression of the calculation result using such a mathematical expression, the combination of the divisor and the quotient can be confirmed at a glance.

  When a divisor group is specified using the divisor group preset key 204, the dividend is input, the remainder calculation key 133 is pressed, the divisor group preset key 204 is pressed, and a plurality of divisor groups can be preset. It is sufficient to operate in the order of selecting / calling and answer key 136 to be pressed, thereby enabling quick input.

  In the above description, the case where a plurality of divisors constituting the divisor group are input (that is, n is an integer of 2 or more) has been described so far. However, after the divisor group designation start key 201 is pressed, the divisor is changed. When the divisor group designation end key 203 is pressed without inputting only one, it may be configured to display an error, or may be configured to display a result by performing a normal remainder operation, You may comprise so that the result may be displayed by performing the normal division in which a calculation result comes out with a decimal. Further, when the answer key 136 is pressed without pressing the divisor group designation end key 203, an error may be displayed, and the numerical value input immediately before the answer key 136 is pressed is the last divisor in the divisor group. It is also possible to configure so that the calculation is executed. Or you may comprise so that the display state of the content of calculation (namely, the divisor group currently designated) may be maintained, without performing calculation.

  In the second embodiment, the divisor group designation start key 201 is pressed, the divisor input and the next divisor designation key 202 are repeatedly pressed, and after the last divisor is entered, the divisor group designation end key 203 is pressed. The configuration in which the divisor group is designated and the batch remainder operation is executed by the procedure described above is described as an example, but the divisor group designation method may be other methods. For example, by providing a key (for example, a key displaying “{}”) for instructing to perform a collective remainder operation, by pressing this button, a plurality of numbers input thereafter can be changed in the collective remainder operation. You may comprise so that it may indicate that it is a divisor group. Then, when actually performing the batch remainder calculation, after the key is pressed first, the divisor input and the next divisor specification key 202 are repeatedly pressed to specify the desired divisor group, and the final divisor is input. The divisor group may be specified by the procedure of depressing the answer key 136 and the batch remainder calculation may be executed.

Further, a reciprocal key for converting a numerical value being displayed into a reciprocal number may be further provided to facilitate the input of fractions and decimals. In addition, you may provide a restriction | limiting in the number of digits which can be handled as a denominator and numerator of a fraction. Similarly, there may be a limit on the number of digits that can be handled for decimal numbers. When setting a limit on the number of digits, it is recommended that numerical values exceeding the limit be handled by approximating the number of digits within the limit by rounding, rounding down, or rounding up. Further, it may be configured such that a circulation decimal number (for example, 1/3, 1/7, etc.) that can be expressed by a fraction can be input.

  Next, an example of an operation method for obtaining a result of the batch remainder calculation by designating a divisor group using the computer 300 will be described. Here, as an example, the case where the dividend is 78/60 (78/60) and the divisors constituting the divisor group are four, 1/2, 1/3, 1/4, and 1/5. explain.

  Prior to starting the calculation, the all clear key 138-2 is pressed to delete the past input contents and calculation results from the storage unit 150. Subsequently, with the numeric input key 131, 6 and 0 are pressed to input 60 as the denominator of the first input value (dividend), and then the numerator input key 301 is pressed to enable the numerator to be input. Then, by pressing 7 and 8 with the numeric input keys 131, 78/60 is input as the dividend.

  Next, the remainder calculation key 133 is pressed to instruct the remainder calculation. Subsequently, the divisor group designation start key 201 is pressed to instruct to input the divisor group in the batch remainder calculation. Next, ½ is input using the numeric input key 131 and the numerator input key 301 in the same manner as the dividend input. Subsequently, when the next divisor designation key 202 is pressed, 1/2 is determined as the first divisor and the second divisor can be input. Then, using the numeric input key 131 and the numerator input key 301, 1/3 is input as the second divisor. Subsequently, when the next divisor designation key 202 is pressed, 1/3 is determined as the second divisor and the third divisor can be input. The same procedure is repeated to input ¼ as the third divisor and 1/5 as the fourth divisor, and press the divisor group designation end key 203 to end the divisor group input. 1/2, 1/3, 1/4, and 1/5 are input as divisors constituting the divisor group.

  Further, when the answer key 136 is pressed, the first division between the dividend 78/60 and the first divisor 1/2 is performed, and the remainder of the first division 18/60 and the second divisor 1 /. The second division with 3, the second division 18/60 and the third divisor 1/4, the third division, the third division remainder 3/60 and the fourth divisor The fourth division with 1/5 is executed.

  The calculation result is stored in the storage unit 150 and displayed on the display unit 120. When a divisor group by n divisors is designated, the calculation result displays n quotients (hereinafter referred to as an integer quotient group) for the 1st to nth divisions and a remainder of the nth division. In the case of the above calculation example, the calculation result is displayed as, for example, “{2, 0, 1, 0} 3/60”. The calculation result may be displayed using a mathematical formula. For example, in the case of the above calculation example, “78/60 = 1/2 × 2 + 1/3 × 0 + 1/4 × 1 + 1/5 × 0 + 3/60” may be displayed on the display unit 120 as the calculation result. According to the expression of the calculation result using such a mathematical expression, the combination of the divisor and the quotient can be confirmed at a glance.
