        If Degree and 're^ theta i' modes are set, a complex result will
return the angle component in Degrees - no problem.

        The problem arises when inputting complex numbers in polar form.
In this operation, the TI-83 _always_ treats the angle component as
being in radians, so when working in degrees, include the conversion
factor. 30 degrees, say, is 30*pi/180 radians; so key 20e^(i30 pi/180)
for the number (20/_30 degrees). If you're doing lots of them, or in a
program, store the conversion factor in a memory, say Z, and key
20e^(i30Z).
