HP HP-32S - The Complex Stack

The Complex Stack
The complex stack is really the regular memory stack split into two
double registers for holding two complex numbers, zlx + iz-^ and
z2x + IZ2y:

Z z

Complex Stack
Since the imaginary and real parts of a complexnumber are entered
and stored separately, you can easily work with or alter either part by
itself.
