Well, -0.0 doesn't work, and (double)0x80000000 doesn't work,
and.... I think you have to use quirks of a compiler to create
it.  And I don't know how to test for it either, x < 0.0 is
not necessarily true for negative 0.

I am not trying to say there is no way to do this.  I am
trying to say it takes thought and effort on every detail,
in the definition, implementations, and unit tests.
