; and : can be used to interconvert the rectangular and polar forms of
a complex number. They operate in Complex mode as follows:
´
;
converts the polar (or phasor) form of a complex number to its
rectangular form by replacing the magnitude r in the real Xregister with a, and replacing the angle θ in the imaginary Xregister with b.

:
converts the rectangular coordinates of a complex number to the
polar (or phasor) form by replacing the real part a in the real Xregister with r, and replacing the imaginary part b in the
imaginary X-register with θ.
These are the only functions in Complex mode that are affected by the
current trigonometric mode setting. That is, the angular units for θ must
correspond to the trigonometric mode indicated by the annunciator
(or absence thereof).
