Comment(by dukeleto):
I am going on the assumption that there "can be only one" NaN. The entity
'NaN' is for encoding the idea that we should represent an invalid
arithmetic operation as something special. There is no "real" NaN and
"complex" NaN. *All* arithmetic operations, no matter they be real or
complex, that contain a NaN should simplify to NaN. The partial patch that
was added to this ticket adds some support for parsing complex numbers of
the form "NaN+2*i" and such, but there are still all kinds of other ways
that you can make either the real or imaginary part of the resulting
number NaN that does not require parsing a string, and these are the cases
where we still have bugs.
Also, the patch attached is quite old and the tests no longer compile, but
it is a good start.
