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°.
