Arne Plöse commented on MATH-577:
---------------------------------

Maybe Im a little dumb, but why are Complex.add and Complex.subtract
differently implemented regarding NaN values?
subtract returns Complex.NaN if there is one of both NaN.

I only found your checkin of revision 280031 where you intoduced NaN in
equals, but cant find anything on commons-dev (maybe I got the wrong
keywords hashCode, equals)?
