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.
To obtain random three-digit integers
RanInt#: Function that generates a pseudo random integer between a
specified start value and end value.
To generate random integers in the range of 1 to 6
nPr, nCr: Permutation (nPr) and combination (nCr) functions.
To determine the number of permutations and combinations possible when
selecting four people from a group of 10
Permutations:
Combinations:
Rnd: Using the Rnd function causes decimal fraction values of the
argument to be rounded in accordance with the current Number Format
