Conditions for Displaying a Calculation Result as a Recurring
Decimal
If a calculation result satisfies the following conditions, pressing
display it as a recurring decimal value.
• 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 value to be displayed as the recurring decimal must be
no larger than 99 bytes. Each value and the decimal point require one
byte, and each digit of the period requires one byte. The following, for
example, would require of total of 8 bytes (4 bytes for the values, 1 byte
for the decimal point, 3 bytes for the period): 0.123.
Note
• For information about switching the display format of a calculation result when OFF is
selected for the Rdec setting on the setup menu, see "Toggling Calculation Results".
