Polar/Rectangular Coordinate
Conversion
Two functions are provided for polar/rectangular coordinate
conversion . To convert values in the X-and Y-registers, (repre-
senting rectangul
ar x, y coordinates , respectively) to polar r,
(J coordi nates (magnitude and angle, respectively), press m ~ .
Magnitude r then appears in the X-register and angle is placed
in the Y-register.
Converse ly , to convert values in the X- and Y- registers (repre-
senting polar r,
(J , respectively) to rectangular coordinates (x , y
respectively), press
0.

with the angle
expressed in radians.
