Abstract

PURPOSE: A method for displaying a cipher as a character and an electronic calculator using the same are provided to correctly read a long number without an error by displaying the character such as ten thousand or a hundred million while displaying a comma to every 3 ciphers in order to keep a standard for a current system. CONSTITUTION: A 'ten thousand' display device and a 'hundred million' display device are installed to the inside of a display tool(10). A cipher judging tool judges that the number is under the hundred million or between the hundred million and the ten thousand. An appointing tool appoints the number over the ten thousand as a high group and the number under the ten thousand as a low group in case that the number is between the hundred million and the ten thousand, and appoints the number over the hundred million as the high group and the number under the hundred million as the low group in the case that the number is over the hundred million. For displaying the high group, a shift ordering tool outputs an instruction for displaying the number by shifting one cipher to left, and displaying the 'ten thousand' display device or the 'hundred million' display device.

Description

Display method of number with characters and a desktop calculator using approximately

The present invention relates to a display device of Arabic numerals, and more particularly, to a display method of displaying the number of digits in letters for Arabic numerals used in electronic calculators, stock quotes, amount display, population display, accounting, and finance, It relates to an electronic calculator.

In general, in the case of a widely used electronic calculator, a single segment is used to represent one number, and a plurality of seven segments are arranged to display a number of thousands or more. In addition, as the number increases, commas (,) are expressed in three-digit units from the job in order to increase readability.

In addition, software in the stock trading market, the homepage of the Internet, accounting and financial fields also use the same method as the electronic calculator when displaying input numbers or calculated results.

However, this method has the following problems. In other words, in Korea, 4 numbers are used repeatedly as basic units from job to 1,000 digits, and every time one unit is increased, distinctive characters such as "million", "billion", "jo" are inserted. . Therefore, in order to easily read the number displayed in such a number system, it is reasonable to display the comma (,) in 4 digits rather than in 3 digits.

For example, in the case of "KRW 254 million," it is represented as "2,745,000,000", so the comma between "2" and "7" is frequently read as "KRW 270 million." . Therefore, if a comma is printed every four digits, it is expressed as "27,4500,0000". Therefore, anyone who reads the numbers at first can read the number "27 billion XXXXXX" easily because the number "27" before the first comma is read as "twenty seven".

Accordingly, in view of the above problems and countermeasures, a method of displaying a comma every four digits has been proposed. However, due to the chaos between the international standard and the pre-existing electronic calculator, it was not widely distributed.

In particular, in the conventional display method, when the displayed number is less than ten thousand units, the read rate does not significantly decrease, whereas the read rate is significantly reduced for ten million units or hundreds of millions of units.

Therefore, the present invention has been made in view of the above problems, and the object of the present invention is to display a comma (,) every three digits in order to maintain the conventional system and standard, By displaying a letter "or" billion ", it is to provide a display method for displaying a number of digits that can be easily and accurately read even a long number without a mistake, and an electronic calculator using the same.

An object of the present invention as described above, preparing a number to be displayed (S10);

<Description of the symbols for the main parts of the drawings>

10: display device, 12: seven segment,

20: "seven" character seven segments, 25: "only" character display device,

30: "segment" character seven segments, 35 "billion" character display device.

Hereinafter, a display method for displaying the number of digits according to the present invention and an electronic calculator using the same will be described in detail with reference to the accompanying drawings.

First, a configuration of a display device for displaying the number of digits according to the present invention as a letter and an electronic calculator using the same will be described in detail with reference to the accompanying drawings. 1 is a front view of a display device 10 of an electronic calculator for displaying a digit by a letter according to the present invention. As shown in FIG. 1, 12 seven segment diodes 12 are arranged in a line, and a comma (,) is displayed every three digits. In the fifth seven segment 12 or more, the "seven" character seven segment 20 is located, and in the nineth seven segment 12 or more, the "billion" character seven segment 30 is located.

FIG. 2 illustrates an example of displaying a series of numbers “45,230” in the display device 10 shown in FIG. 1 as an example. That is, FIG. 2 illustrates a case where a series of numbers represents a number between 10,000 and billion units. Among the "45,230" displayed as an example, "4" is designated as a high group, "5230" is designated as a low group, and the high group "4" is shifted to the left of the Hangul character and displayed. The light of "only" is displayed. In this case, the person who reads the displayed number at first glance reads "40,000" as "Saman", so there is almost no chance of misreading the number.

3 illustrates an example of displaying a series of numbers “2,745,000,000” in the display device 10 illustrated in FIG. 1. As shown in FIG. 3, the "27" character is designated as a high group and displayed by moving to the left one by one by Korean characters, and the "100 million" character of the "segment" seven segment 30 emits light. At this time, "only" characters are not displayed. Therefore, even a person reading a high number as shown in FIG. 3 reads "2.7 billion" as "twenty-seven billion", so there is no fear of mistaken numbers.

FIG. 4 is a diagram illustrating a seven segment 20 positioned at a tenth position of the display device 10 illustrated in FIG. 1. As shown in FIG. 4, the seven segment 20 located at the ten thousand position is largely composed of a seven segment 12 and a "man" character display device 25. These light emission (or lighting, flashing) are independently processed by the driving IC or the like.

In particular, the "man" character display device 25 is preferably composed of the same diode as the seven segment 12, and is located in the lower margin of the interior of the seven segment 12 composed of "8" characters.

FIG. 5 is a diagram illustrating a seven segment 30 positioned at one billion or more positions of the display device 10 shown in FIG. 1. As shown in FIG. 5, the seven segment 30 located over one billion digits is largely composed of the seven segment 12 and the "man" and "billion" display devices 35. These light emission (or lighting, flashing) are independently processed by the driving IC or the like.

In particular, the "man" character and "billion" character display device 35 is preferably composed of a diode of the same material as the seven segments 12, and the "man" character is the inside of the seven segment 12 composed of "8" characters. It is located at the bottom margin, and the "billion" is located in the upper margin of the interior of the seven segment 12 consisting of "8".

Hereinafter will be described in detail with respect to the operation method of the electronic calculator to display the digits having the configuration as described above as a letter. 6 is a flowchart of a display method of an electronic calculator for displaying a digit by a letter according to the present invention. As shown in FIG. 6, first, numbers to be displayed are prepared (S10). This preparatory step is to read the numeric data stored in the memory, register, etc. to read the numerical results stored in the memory, register, etc., if you want to display the number input by the key input unit (not shown), etc. This is a typical case.

Then, it is determined whether the series of numbers is less than ten thousand digits (S20).

If the series of numbers is less than ten thousand digits, the corresponding number is displayed (S30). If more than ten thousand digits are determined, it is determined whether between ten thousand and hundred million digits (S40). If the series of numbers is less than ten thousand digits, it is not necessary to display "ten thousand" or "billion" characters, and so on.

If the number is between ten thousand and hundred million digits, "only" character is displayed (S50). A detailed step of displaying "only" characters will be described in detail with reference to FIG. 7.

Next, when the number is 100 million digits or more, "100 million" characters are displayed (S60), and the detailed steps of displaying "100 million" characters will be described in detail with reference to FIG. 8.

Hereinafter, the detailed steps of the step S50 of displaying “only” characters will be described in detail with reference to FIG. 7. FIG. 7 is a detailed flowchart of the “only” digit display process S50 of FIG. 6. As shown in FIG. 7, first, at least 10,000 digits of the series of numbers are designated as a high group, and less than 10,000 digits of the numbers are designated as a low group (S52).

That is, for example, when it is desired to display "45230" as shown in FIG. 2, "4" is designated as a high group and "5230" is designated as a low group.

Then, "5230" corresponding to the row group is displayed in the corresponding digit. That is, "5" is displayed on the thousandth place, "2" on the hundredth place, "3" on the tenth place, and "0" on the job place.

Next, a "man" diode 25 as shown in FIGS. 1 and 4 is shown. As such, the word "only" is expressed in the display device and visually identified.

Next, the letter "4" corresponding to the high group is shifted by one digit to the left (a hundred thousand digits) from the corresponding digit (10 thousand digits in the present embodiment) and then displayed (S54). Therefore, the displayed "45230" is displayed from 100,000 digits, an example of the display is "45,230". Therefore, at first glance, the possibility of reading "400,000XXXXX" or "SichuanXXXX" is almost slim because the first part of the series is read as "400,000XXXXX".

Hereinafter, with reference to FIG. 8 will be described in detail the detailed steps of the step (S60) for displaying the "billion" characters. FIG. 8 is a detailed flowchart of the “billion” digit display process S60 of FIG. 6. As shown in FIG. 8, first, one billion or more of the series of numbers are designated as a high group, and less than one billion of the numbers are designated as a low group (S62).

That is, for example, when "2745000000" is to be displayed as shown in FIG. 3, "27" is designated as a high group and "45000000" is designated as a low group.

Then, "45000000" corresponding to the row group is displayed in the corresponding digit. That is, "4" is displayed in ten million digits, "5" in one million digits, and "0" is displayed for all digits. At this time, the "only" character is emitted and is not displayed.

Next, the " only " and " billion " diodes 35 as shown in Figs. 1 and 5 are shown. As such, the letter "billion" is represented in the display device and visually identified.

Next, the "27" characters corresponding to the high group are shifted by one digit (left billion digits) from the corresponding digits (billion digits in this embodiment) to the left and displayed (S64). Therefore, the displayed "2745000000" is displayed from 10 billion digits, and one example displayed is "2,750,000,000." Thus, at first glance, it is almost unlikely to read "200 billion XXXX" or "200 billion XXXX" because the first part of the series is read as "2.5 billionXXXXX".

Although the display device in which the number of digits of the present invention is represented by a letter has been described as an example of an electronic calculator in the embodiment, it can be suitably used to express various numerical information such as stock price, finance, insurance, accounting, and population on the web of the Internet. In the off-line, it can be applied to electronic calculators, mobile phones, signs, etc.

In addition, the display element of the present invention can be applied to the display element without limitation as long as the number can be expressed, such as liquid crystal, LED, LCD, diode, organic EL, fluorescent matrix, and the like.

In the present invention, "only" and "billion" characters are expressed, but some characters may be further expressed as necessary.

When the present invention is to be realized in an electronic calculator, the display method according to the present invention is implemented by using a mechanical language such as a built-in microcomputer. Due to the program of the instruction, the microcomputer determines the number of digits to determine whether the series of numbers is less than one billion digits and between tens and hundreds of digits;

Based on the judgment result of the determining means, if the number is between ten thousand and hundred million digits, ten thousand digits or more are designated as a high group, and less than ten thousand digits are designated as a low group; Designation means for designating an abnormality as a high group and a less than billion digits as a low group; And

A function of moving command means for outputting a command to display the "only" character display device 25 or the "billion character display device 35" by moving left one by one digit when displaying the high group. Done.

As described above, according to the display method for displaying the number of digits according to the present invention and an electronic calculator using the same, in order to maintain the conventional system and standard, a comma (,) is displayed every three digits, By displaying the letters "only" or "billion", even a long number has a feature that can be easily and accurately read without mistakes.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, various other modifications and variations may be made without departing from the spirit and scope of the invention. It is therefore contemplated that the appended claims will cover such modifications and variations as fall within the true scope of the invention.
