Pol, Rec: Pol converts rectangular coordinates to polar coordinates, while
Rec converts polar coordinates to rectangular coordinates.
Specify the angle unit before
performing calculations.
The calculation result for r and θ
and for x and y are each
assigned respectively to
variables x and y.
Calculation result θ is displayed
in the range of -180° < θ 180°.

Ran#: Function that generates a pseudo random number in the range of
0.000 to 0.999. The result is displayed as a fraction when MathI/MathO is
selected for Input/Output on the setup menu.

Rnd: Using the Rnd function causes decimal fraction values of the
argument to be r
ounded 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.
To perform the following calculations when Fix 3 is selected for the number
of display digits: 10 ÷ 3 × 3 and Rnd(10 ÷ 3) × 3 (MathI/DecimalO)
