Important!
If the value starts with an integer part (like: 12.3123123...), do not include the integer
part when inputting the period (12.312).
Recurring decimal input is possible only when MathI/MathO or MathI/DecimalO is
selected for Input/Output on the SETTINGS menu.
Recurring Decimal Calculation Example
To calculate 3.
021 + 0.312 (Input/Output: MathI/MathO)
1. Use the following operation to input the calculation expression.
3 ( ) 021
0 ( ) 312
This displays the calculation result as a fraction.
2. Press , and then select [Recurring Decimal].
This changes the result format to recurring decimal.
To return the calculation result to a fraction, select [Standard].
Note
Only a calculation result that satisfies the conditions below can be displayed as a
recurring decimal.
- The total number of digits used in the mixed fraction (including integer, numerator,
denominator, and separator symbol) must be no more than 10.
- The data size of the value when displayed as a recurring decimal must be no larger
than 99 bytes, calculated as: [number of digits (1 byte each)] + [1 byte for the
decimal point] + [3 bytes for recurring decimal management code]. For example, the
data size of 0.
123 would be 4 bytes for digits, 1 byte for the decimal point, and 3
bytes for recurring decimal management code, for a total of 8 bytes.
