The IEEE spec absolutely thinks that -0 and +0 are distinct entities.
I don't remember why, at one in the morning ... but if you insist I'm
sure that plenty sufficient numerical-analysis reasons can be produced.
The guys who wrote that spec knew what they were doing (that's why it's
been adopted so universally).
