Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ratio display control device, a program, and a ratio display control method for displaying the ratio of each component to the total value of a plurality of components.

[0002]

2. Description of the Related Art Conventionally, a graph scientific calculator equipped with a graph creating and displaying function has been used in the field of education and for technical calculation of engineers. This graph scientific calculator has various function calculation programs built-in, and it is possible to create and display a graph based on an input mathematical expression or numerical value.

For example, a case will be described in which input data is displayed as a percentage by using this graph scientific calculator. In this case, first, when “input of list data” is instructed from the input unit, a data input screen (not shown) is displayed on the display unit. Next, as in the input example shown in FIG. 8, the list data components (A =
“5”, B = “4”, C = “3”, D = “2”, E =
"1") is input from the input unit. Then, when the "display of percentage" is instructed from the input unit, the percentage of each component of the input list data is calculated, and as shown in FIG. 9, the percentage of each component (here, A: "33. 33% ", B:
"26.66%", C: "20.00%", D: "1"
3.33% ", E:" 6.66% ") is displayed on the display unit by a numerical value or a pie chart 7.

FIG. 9 shows a display example when there is a limitation such that the range (digits) of the numerical value displayed on the display unit is up to the second decimal place, and the third decimal place is cut off. In this case, the total of the percentages of the plurality of components A to E is 99.98%. That is, as shown in FIG. 10, the ratio of the entire list data (the total value of the plurality of components A to E) should be 100%, but the total percentage of the plurality of components does not reach 100%. Occurs.

In another example, as components of list data, A = “500”, B = “500”, C = “45”.
When “0” is input from the input unit, the percentage of each component A to C with respect to the entire list data (total value of the plurality of components A to C) is A: “34.48275” as shown in FIG.
862% ", B:" 34.48275862% ", C:
It becomes "31.03448276%". Here, when the percentage of each component is rounded off to the third decimal place, as shown in FIG. 12, A: “34.48%”, B: “34.48%”.
% "And C:" 31.03% ", and the total percentage of each component becomes 99.99%.

In other words, even if rounding is performed by rounding,
In some cases, the total percentage of each component does not add up to 100%. Therefore, for example, it is not suitable for educational sites such as elementary schools.

“34.48275862%”, B: “34.4827
5862% "and C:" 31.03448276% ". Therefore, A: “2”, B: “2”, and C: “4” are respectively stored in the third decimal place storage area 5b as the third decimal place from the percentage of each component (step S).
1).

Next, the CPU 1 rounds down the third decimal place of the percentage of each component and outputs the total of each percentage. In other words, each percentage is A = "34.48%", B
= “34.48%”, C = “31.03%”, and the total is calculated as A + B + C = “99.99%” (step S2). Then, the CPU 1 sets the count value n
Is set to 1 and stored in the RAM 5 (step S3), and it is determined whether the total percentage of each component is 100% (step S4).

Here, the total percentage of each component is 100%.
If not (step S4; No), the third decimal point
Of the third decimal place stored in the rank storage area 5b, the nth largest data (for example, the 1st largest data,
C: "4") is corrected by adding "1" to the second decimal place of the percentage of the component, that is, C: "31.03% → 31.0.
4% ”(step S5). And the CPU 1
The count value n is incremented and stored in the RAM 5 (step S6), and the process returns to step S4.

In step S4, if the total percentage of each component is 100% (step S4; Y
es), as shown in FIG. 5, the percentage of each component (A: “3
4.48% ", B:" 34.48% ", C:" 31.0 "
4% ”) is displayed on the display unit 4 as a numerical value or a pie chart 7 (step S7), and the percentage display processing is terminated.

As described above, when displaying the percentage of each component of the list data input from the input unit 2, the CPU 1 of the calculator 100 according to the present embodiment calculates the percentage of each component of the list data, The third decimal place of each calculated percentage is stored in the third decimal place storage area 5b. Further, the CPU 1 rounds down the third decimal place of the percentage of each component of the list data, outputs the total of each percentage, and determines whether or not the total becomes 100%. If this total does not reach 100%, the component with the third largest decimal point value stored in the third decimal place storage area 5b is arranged in order from the largest decimal point second component.
The value is corrected by adding "1" to the position, and this correction is repeated until the total of the percentages of the respective components reaches 100%. Then, when the total of the percentages reaches 100%, the percentages of the respective components are displayed on the display unit 4 as numerical values or a pie chart 7.

Therefore, the total of the percentages of the respective components of the list data can be set to 100%, and the device suitable for use in the educational field can be provided.

For example, when the ratio of each component to the entire data (total value of a plurality of components) is displayed. May be applied to. In particular,
This can be applied when displaying the ratio of each component when the entire list data is 1. Further, it can be applied when displaying a breakdown (ratio) of components that occupy 20% of the entire list data. In this case, the ratio of each component may be corrected so that the total of the ratios of the plurality of components becomes a predetermined total ratio that can be set arbitrarily.

Further, in the present embodiment, the fractions below the third place of the percentage of each component of the list data are rounded down, and the correction is made based on the total percentage of each component up to the second decimal place. However, it is not limited to this. For example, the third decimal place of the percentage of each component is stored in the RAM 5 in association with each component, the second decimal place is rounded up, and the third decimal place and below are discarded.
Then, when the sum of the percentages of the respective components does not reach 100%, the third decimal point corresponding to the respective components stored in the RAM 5
The component may be corrected by subtracting “1” from the second decimal place of the component in order from the smallest component.

Further, for example, by rounding off or rounding off, the percentage of each component of the list data is rounded to the number of digits to be displayed on the display unit 4, and the total of each rounded component is 100%.
(Or a predetermined total rate), it may be corrected. In this case, correction may be made by adding or subtracting the value of the least significant digit of each component until the ratio of each rounded component reaches 100% (or a predetermined total rate).

Further, in the present embodiment, an example of displaying up to the second decimal place is described, but the present invention is not limited to this, and an arbitrary display digit is displayed within a displayable range on the display unit 4. It may be applied in some cases.

Further, for example, the component having the highest ratio or the component having the lowest ratio among the plurality of components may be the correction target.

Further, in the present embodiment, the case where the percentage is displayed by the numerical value or the pie chart 7 has been described, but the present invention is not limited to this, and as shown in FIG. 6 and FIG. May be displayed. here,
In FIG. 6, as the components of the list data, A = “5”, B =
