Thank you.  It appeards like the current implementation is conforming.

Well, the current behaviour makes perfect sense if we assume that a floating
point value has exact zero imaginary part.  Conceptually, now we have three
zeros: -0.0, the curiously half baked mixture of +0.0 and 0.0 and also an exact
zero.  Crazy.
