Inconsistent Deg/Rad in CAS

[GregP]

I believe that version is the last one which behaves consistently in CAS when in degree mode and complex numbers are used with ARG().

The only other interesting thing I noticed is that the dedicated complex variables Z0...Zx will truncate any mantissa of the imaginary part if it is zero on entry and then correctly display degrees when ARG() is used.

My understanding of this situation is that CAS mode does not store complex numbers as an object. Doing so (with perhaps a preferred display flag) would make the lives of electrical engineers and EE students a lot easier (as would allowing i to be j - but that second item is easy to fix in CAS by entering j:=(0,1) )
