Recurring Decimal

You can use ( ) or the menu item below to input a recurring
decimal.

Round Off

Using the Round Off function (Rnd) causes decimal fraction values of the
argument to be rounded in accordance with the current Number Format
setting. For example, the internal and displayed result of Rnd(10 ÷ 3) is
3.333 when the Number Format setting is Fix 3. Using the Norm 1 or Norm
2 setting cause the argument to be rounded off at the 11th digit of the
mantissa part.
Example: To perform the following calculations when Fix 3 is selected for
the number of display digits: 10 ÷ 3 × 3 and Rnd(10 ÷ 3) × 3
(Input/Output: MathI/DecimalO, Number Format: Fix 3)
