Q3Point2D_ToPolar

You can use the Q3Point2D_ToPolar function to convert a two-dimensional point from Cartesian form to polar form.

TQ3PolarPoint *Q3Point2D_ToPolar (
const TQ3Point2D *point2D, 
TQ3PolarPoint *result);

point2D

A two-dimensional point.

result

On exit, a polar point.

DESCRIPTION

The Q3Point2D_ToPolar function returns, as its function result and in the result parameter, a polar point that is the same point as the two-dimensional point specified by the point2D parameter.
