Recurring Decimal Calculations
Your calculator uses a recurring decimal when you input a value.
Calculation results also can be displayed using recurring decimal form
whenever applicable.
Inputting a Recurring Decimal
When inputting a recurrent decimal, press
( ) before inputting its
period (repetend) and then input the period up to the ending value. To
input the recurring decimal 0.909090.... (0.90), perform the following
operation: “0 ( ) 90”.
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 setup menu.
Example 1: To input 0.33333… (0.
