Description

METHOD OF DISPLAYING NUMBER AS CHARACTER AND ELECTRONIC CALCULATOR USING THE SAME
Technical Field
The present invention relates to a display device using Arabic numerals, and more particularly, to a method of displaying as characters numbers used in electronic calculators, sharelists, the amount of money, the number of population, and accounts and financial fields, and an electronic calculator using the same.
Background Art
Generally, in a widely used electronic calculator, a number is expressed using a seven segment, and numbers of four or five digits or more are expressed by marshaling a plurality of seven segments. Also, as more digits are added, comma (,) is used for every three digits to improve readability.
This method used in a typical electronic calculator is also applied to sharelists, Internet homepages, and accounts and financial software to display input numbers or calculated results. However, the above method is not adequate for the Oriental unique number reading system. That is, according to the Oriental system, when a number is read, every four digits are used as a basic unit. Whenever every four digits are added, additional characters, such as "Maan", "Uck", and "Cho,"(Korea), "Man", "Oku", and "Chou"(Japan), and "Wan", "Yi", and "Zhau" (China) are inserted to read the number. Here, "Maan", "Man", and "Wan" refer to ten thousand, "Uck", "Oku", and "Yi" refer to hundred millions, and "Cho", "Chou", and "Zhau" refer to thousand billons. Accordingly, in this number reading system, it is more desirable to use a comma for every four digits instead of every three digits, to improve the readability.
For example, "twenty-seven Uck four thousand and five hundred Maan won" (Korea) is displayed as " 2,745,000,000", which is frequently mistakenly read in Korea as "two Uck seven thousand, four hundred and fifty Maan won" because of a comma used between "2" and "7". If the "twenty-seven Uck four thousand and five hundred Maan won" is expressed by using a comma for every four digits, it can be displayed as " 27,4500,0000". In this case, even a user reading the number roughly or carelessly can easily recognize the number as approximately "twenty-seven Uck won" because of "27" used before the first comma. To solve the above problem, a method of using a comma (,) for every four digits has conventionally been proposed. However, this method is not widely used because of the international standard and the difficulty of application to already spread electronic calculators.
In particular, whereas this conventional method is effective in ten thousand or less (i.e., a Maan or less), the readability is markedly lowered in numbers of many digits, such as ten millions (i.e., thousand Maan) or hundred millions (i.e., an Uck).
Disclosure of the Invention The present invention provides a method of displaying numbers as characters and an electronic calculator using the same. In this method, while a comma (,) is used for every three digits so as to comply to the conventional number reading system and standard, a character such as "Maan" (ten thousand) or "Uck" (hundred millions) is displayed right before a series of figures consisting of a number such that even numbers of many digits can be easily and exactly read.
In accordance with an aspect of the present invention, there is provided a method of displaying numbers as characters, comprising preparing a number to be displayed (S10); determining whether or not the number is a four-digit number or less (S20); displaying the number as it is if it is determined that the number is a four-digit number or less (S30), and determining whether the number is between four-digit numbers and nine-digit numbers or the number is a nine-digit number or more if it is determined that the number is a five-digit number or more (S40); displaying the number as the character "Maan"(ten thousand) if it is determined that the number is between four-digit numbers and nine-digit numbers (S50); and displaying the number as the character "Uck" (hundred millions) if it is determined that the number is a nine-digit number or more (S60). the displaying of the character "Maan" (S50) may comprise classifying figures consisting of the number, which are in five digits or more, into a high group and classifying the other figures consisting of the number, which are in four digits or less, into a low group (S52); and displaying the low group in corresponding digits, displaying a diode of the character "Maan", displaying the high group by taking the figures up one place (S54).
The displaying of the character "Uck" (S60) may comprise classifying figures consisting of the number, which are in nine digits or more, into a high group and classifying the other figures consisting of the number, which are in eight digits or less, into a low group (S62); and displaying the low group in corresponding digits, displaying a diode of the character "Uck", displaying the high group by taking the figures up one place (S64).
In accordance with another aspect of the present invention, there is provided a displaying unit for displaying a series of figures consisting of a number. The displaying unit comprises a character "Maan" displaying portion; a character "Uck" displaying portion; a digit determining portion for determining whether the number is an eight-digit number or less or the number is between four-digit numbers' and nine-digit numbers; a classifying portion for classifying figures consisting of the number, which are in five digits or more, into a high group and classifying the other figures consisting of the number, which are in four digits or less, into a low group if it is determined that the number is between four-digit numbers and nine-digit numbers and for classifying figures consisting of the number, which are in nine digits or more, into a high group and classifying the other figures consisting of the number, which are in eight digits or less, into a low group if it is determined that the number is a nine-digit number or more; and a movement commanding portion for outputting commands such that the high group is displayed by taking the figures up one place and the character "Maan" displaying portion or the character "Uck" displaying portion displays the character "Maan" or "Uck".
In accordance with yet another aspect of the present invention, there is provided an electronic calculator including the displaying unit and for displaying numbers as characters.
Also, the displaying unit may be one of a diode using a seven segment, an LCD, an LED, and an organic EL. The character "Maan" displaying portion and the character "Uck" displaying portion may be located in blanks of corresponding seven segments.
The above object and advantages of the present invention will become more apparent by describing in detail preferred embodiments thereof with reference to the attached drawings.

Best mode for carrying out the Invention
Hereinafter, a method of displaying numbers as characters and an electronic calculator using the same will be described in detail with reference to the appended drawings.
FIG. 1 is a front view of a displaying unit 10 of an electronic calculator, which displays numbers as characters, according to the present invention. As shown in FIG. 1 , 12 seven segment diodes 12 are arranged in one row, and a comma (,) is used for every three digits. A character "Maan"(ten thousand) seven segment 20 is located in fifth-digit and higher seven segments 12, and a character "Uck"(hundred millions) seven segment 30 is located in ninth-digit and higher seven segments 12.
FIG. 2 is the displaying unit 10 shown in FIG. 1 , which exemplarily illustrates a five-digit number "45,230". The number 45,230 belongs between four-digit numbers and nine-digit numbers. Among figures consisting of the number 45,230, a figure "4" is classified into a high group and the other figures "5", "2", "3", and "0" are classified into a low group. The figure "4" classified into the high group is taken up one place and displayed, and a character "Maan" is displayed by emitting light in the character "Maan" seven segment 20. Here, even a user who sees the displayed number roughly or carelessly can easily recognize the number as approximately forty thousand. Thus, a likelihood of misreading numbers from the displaying unit is markedly reduced.
FIG. 3 is the displaying unit 10 shown in FIG. 1 , which exemplarily illustrate a ten-digit number "2,754,000,000". As shown in FIG. 3, figures "2" and "7" are classified into a high group and taken up one place, and a character "Uck" is displayed by emitting light in the character "Uck" seven segment 30. Here, the character "Maan" is not displayed. Accordingly, even a user who sees such a high number as the number 2,754,000,000 carelessly can easily recognize the number as approximately two billions and seven hundred thousand. Thus, a likelihood of misreading the number is markedly reduced.
FIG. 4 is a diagram of the character "Maan" seven segment 20 of the displaying unit shown in FIG. 1. As shown in FIG. 4, the character "Maan" seven segment is composed of the seven segment 12 and a character "Maan" displaying portion 25. The seven segment 12 and the character "Maan" displaying portion 25 emit light or are turned on and off independent of each other by a driving IC.
The character "Maan" displaying portion 25 preferably includes a diode formed of the same material as one seven segment 12 and the character "Maan" is located in a lower blank of the 8-shaped seven segment 12.
FIG. 5 is a diagram of the character "Uck" seven segment of the displaying unit 10 shown in FIG. 1. As shown in FIG. 5, the character "Uck" seven segment 30 is composed of one seven segment 12 and a character "Maan" and "Uck" displaying portion 35. The seven segment 12 and the character "Maan" and "Uck" displaying portion 35 emit light or are turned on and off independent of each other by a driving IC.
The character "Maan" and "Uck" displaying portion 35 preferably includes a diode formed of the same material as the seven segment 12. The character "Maan" is located in a lower blank of the 8-shaped seven segment 12, and the character "Uck" is located in an upper blank thereof. Hereinafter, a method of operating the electronic calculator, in which digits are displayed as characters, will be described in detail. FIG. 6 is a flowchart illustrating the operation of the electronic calculator according to the present invention. As shown in FIG. 6, initially, a number to be displayed is prepared (S10). Numbers are prepared, for example, to display numbers input by a key input portion (not shown), results calculated by a microcomputer or a CPU, and numerical data stored in a memory or a register.
Next, it is determined whether or not the number is a four-digit number or less (S20). If it is determined that the number is a four-digit number or less, the number is displayed as it is (S30). If it is determined that the number is a five-digit number or more, it is determined whether or not the number is between four-digit numbers and nine-digit numbers (S40). If the number is a four-digit number or less, it can be displayed in a conventional method.
If it is determined that the number is between four-digit numbers and nine-digit numbers, a character "Maan" is displayed (S50). The displaying of the character "Maan" will be described in more detail later with reference to FIG. 7. Next, if it is determined that the number is a nine-digit number or more, a character "Uck" is displayed (S60). The displaying of the character "Uck" will be described in more detail later with reference to FIG. 8.
FIG. 7 is a detailed flowchart illustrating the displaying (S50) of the character "Maan". As shown in FIG. 7, figures consisting of the number, which are in five digits or more, are classified into a high group, and the other figures consisting of the number, which are in four digits or less, are classified into a low group (S52).
For example, when the number "42530" shown in FIG. 2 is displayed, the figure "4" is classified into the high group and the figures "5", "2", "3", and "0" are classified into the low group. Next, the figures "5", "2", "3", and "0", which belong to the low group, are displayed in corresponding digits. That is, the figure "5" is displayed in the fourth digit, "2" is displayed in the third digit, "3" is displayed in the second digit, and "0" is displayed in the first digit. Next, the character "Maan" diode 25 is displayed as shown in
FIGS. 1 and 4. Thus, the character "Maan" is displayed in the displaying unit and thus visible to the naked eyes.
Next, the figure "4" which belongs to the high group is taken up one place from its corresponding digit (from the fifth digit to the sixth digit in the present embodiment) and then displayed (S54). Thus, the number "45230" is displayed as, for example, "4Maan5,230" using the first through fifth digits. Accordingly, even if a user sees the number carelessly, the number can be easily recognized as approximately forty thousand. Thus, a likelihood of misreading the number as four thousand or four hundred thousand is extremely low.
FIG. 8 is a detailed flowchart illustrating the displaying (S60) of the character "Uck". As shown in FIG. 8, figures consisting of the number, which are in nine digits or more, are classified into a high group, and the other figures consisting of the number, which are in eight digits or less, are classified into a low group (S62).
For example, when the number "2745000000" shown in FIG. 3 is displayed, the figures "2" and "7" are classified into the high group and the figures "4", "5", "0",..., and "0" are classified into the low group.
Next, the character "Maan" and "Uck" diode 35 is displayed as shown in FIGS. 1 and 5. Thus, the character "Uck" is displayed in the displaying unit and thus visible to the naked eyes.
Next, the figures "2" and "7", which belong to the high group, are taken up one place from their corresponding digits (from the fifth and sixth digits to the sixth and seventh digits in the present embodiment) and then displayed (S64). Thus, the number "2745000000" is displayed as, for example, "2,7Uck45,000,000" using the first through eleventh digits. Accordingly, even if a user sees the number carelessly, the number can be easily recognized as approximately two billions and seven hundred millions. Thus, a likelihood of misreading the number as two hundred and seventy millions or twenty-seven billions is extremely low.
As explained thus far, in a method of displaying numbers as characters and an electronic calculator using the same according to the present invention, while a comma (,) is used for every three digits to comply to the conventional system and standard, a character "Maan" or "Uck" is displayed before a series of figures. Thus, even a number of many digits can be easily and exactly read.
While the present invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
Industrial Applicability
Although the displaying unit for displaying numbers as characters is used in the electrical calculator in the present embodiment, it can be also applied to not only display various online numerical data, such as stock prices, finances, insurances, accounts, and populations, but also to offline electronic calculators, cellular phones, and signboards.
Also, the present invention can be applied to various display devices of displaying numbers, such as liquid crystal devices, LEDs, LCDs, diodes, organic ELs, fluorescent matrixes.
Also, although only characters "Maan" and "Uck" are used in the present invention, other characters may be further used if necessary.
A method of displaying numbers according to the present invention can be embodied in an electronic calculator by applying a machine language to a microcomputer embedded in the electronic calculator. By using programmed command language, the microcomputer can function as a digit determining portion, which determines whether a number is an eight-digit number or between four-digit numbers and nine-digit numbers; a classifying portion, which classifies figures consisting of the number, which are in five digits or more, into a high group if the number is between four-digit numbers and nine-digit numbers and classifies the other figures consisting of the number, which are in four digits or less, into a low group if the number is a eight-digit number or less, the classifying portion which classifies figures consisting of the number, which are in nine digits or more, into a high group if the number is a nine-digit number or more and classifies the other figures consisting of the number, which are in eight digits or less, into a low group if the number is a eight-digit number or less; and a movement commanding portion, which outputs commands such that the high group is displayed by taking the figures up one place and the character "Maan" displaying portion 25 or the character "Uck" displaying portion 35 display the character "Maan" or "Uck".

Claims

What is claimed is:
1. A method of displaying numbers as characters, the method comprising: preparing a number to be displayed (S10); determining whether or not the number is a four-digit number or less (S20); displaying the number as it is if it is determined that the number is a four-digit number or less (S30), and determining whether the number is between four-digit numbers and nine-digit numbers or the number is a nine-digit number or more if it is determined that the number is a five-digit number or more (S40); displaying the number as the character "Maan"(ten thousand) if it is determined that the number is between four-digit numbers and nine-digit numbers (S50); and displaying the number as the character "Uck"(hundred millions) if it is determined that the number is a nine-digit number or more (S60).
2. The method of claim 1 , wherein the displaying of the character "Maan" (S50) comprises: classifying figures consisting of the number, which are in five digits or more, into a high group, and classifying the other figures consisting of the number, which are in four digits or less, into a low group (S52); and displaying the low group in corresponding digits, displaying a diode 25 of the character "Maan", displaying the high group by taking the figures up one place (S54).
3. The method of claim 1 or 2, wherein the displaying of the character "Uck" (S60) comprises: classifying figures consisting of the number, which are in nine digits or more, into a high group, and classifying the other figures consisting of the number, which are in eight digits or less, into a low group (S62); and displaying the low group in corresponding digits, displaying a diode 35 of the character "Uck", displaying the high group by taking the figures up one place(S64).
4. An electronic calculator which displays numbers as characters and includes a displaying unit for displaying a series of figures consisting of a number, wherein the displaying unit comprises: a character "Maan"(ten thousand) displaying portion 25; a character "Uck"(hundred millions) displaying portion 35; a digit determining portion for determining whether the number is an eight-digit number or less or the number is between four-digit numbers and nine-digit numbers; a classifying portion for classifying figures consisting of the number, which are in five digits or more, into a high group and classifying the other figures consisting of the number, which are in four digits or less, into a low group if it is determined that the number is between four-digit numbers and nine-digit numbers and for classifying figures consisting of the number, which are in nine digits or more, into a high group and classifying the other figures consisting of the number, which are in eight digits or less, into a low group if it is determined that the number is a nine-digit number or more; and a movement commanding portion for outputting commands such that the high group is displayed by taking the figures up one place and the character "Maan" displaying portion 25 or the character "Uck" displaying portion 35 displays the character "Maan" or "Uck".
5. The electronic calculator of claim 4, wherein the displaying unit is one of a diode using a seven segment 12, an LCD, and an LED, and wherein the character "Maan" displaying portion 25 and the character "Uck" displaying portion 35 may be located in blanks of corresponding seven segments 20 and 30, respectively.
