Fraction Format Calculation Results
A calculation result whose total number of mixed fraction number of digits (including integer, numerator, denominator, and separator symbol ) is greater than 10 cannot be displayed using fraction format. In this case, the calculation result is displayed as a decimal value.
Example 1: 11
123456 = 123457
123456
(Input/Output: LineI/LineO)
- 1
1
123456
Since the total number of digits of the value 11
123456 is 10, the result is displayed as a fraction value.
Example 2: 11
1234567 (= 1234568
1234567) = 1.00000081
(Input/Output: LineI/LineO)
- 1
1
1234567
Since the total number of digits of the value 11
1234567 is 11, the result is displayed as a decimal value.
Note
Mixing fractions and decimal values in a calculation while something other than MathI/MathO is selected will cause the result to be displayed as a decimal value.
