Example: To generate random integers in the range of 1 to 6
– [Probability] > [Random Integer]

Numeric Calculations

This section explains commands and functions that you can input after
performing the operation:

Absolute Value

When you are performing a real number calculation, this function simply
obtains the absolute value.
Example: |2 - 7| = Abs(2 - 7) = 5
(Input/Output: MathI/MathO)
– [Numeric Calc] > [Absolute Value]
(Input/Output: LineI/LineO)
– [Numeric Calc] > [Absolute Value]

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)
1 (,)6
(The result differs with each execution.)
