R8Pr( converts rectangular coordinates to polar

coordinates and returns r. R8Pq( converts rectangular

coordinates to polar coordinates and returns q. x and y can

be lists.

R8Pr(x,y), R8Pq(x,y)

Note: Radian mode is set.

P8Rx( converts polar coordinates to rectangular

coordinates and returns x. P8Ry( converts polar

coordinates to rectangular coordinates and returns y. r and

can be lists.
