Subj: Complex units
Date: Tue Mar 12 1991
Is there any way to use units on complex numbers? I was doing some
engineering-type stress calculations with complex numbers and was quite
frustrated when I couldn't use units. When the calculations are really
involved and use a lot of equations is when you *really* want to check units
to see if you're right, and I can't.
Is there a conceptual difficulty with complex numbers having units? I mean, is
the complex number (1_m, 1_m) mathematically meaningless? Or is it just a
quirk in the HP's unit management?
Any advice would be appreciated.

There's no conceptual problem with complex numbers with units. The 48 doesn't
happen to include an object type for such things; call it a limitation rather
than a quirk (remember ROM is full and life is short?). However, you can enter
expressions like '(1_m,1_m)', which immediately compiles to '1_m+(1_m)*i'.
That opens up lots of possibilities.
