I'd be interested to know what IDL does?  Does it compare complex

Matlab allows comparisons of complex numbers but just compares the real
part.  I think this is reasonable.  Often during a calculation of
limited precision one ends up with a complex number when the result is
in a "mathematically pure sense" real.  

I guess I trust the user to realize that if they are comparing numbers
they know what they mean --- (only real numbers are compared so the
complex part is ignored).
