      IMPRODUCT() is suppose to calculate products of complex numbers.
However, its answers are not correct: only the real portion of the
complex numbers seem to be used.

           = 4 +i4 -i4 -(4)          [i2*i2=-4]
           = 8
But Calc lists the answer as 4.

      Are there any complex functions that really work other than
IMREAL()? (It only reads the real part of a complex number.


I confirm this result with, Ubuntu 12.04

Excuse me, but I believe the terms +2*i2 and -2+i2 do in fact cancel each other out.
This leaves 2*2 and -(-4) as the remaining terms, or 4 + 4 = 8.

Or, have I missed something?
