The only correct solution would be to strip floating point types of their instances for Ord, Eq, and--therefore, by extension--Num. For some reason, no one else seems to like that idea. I can't imagine why...
I'm not terribly opposed to it. But then, I've also defined classes for partial orderings[1] and for types containing transfinite values[2] in order to try to render floats usable. Also, don't forget some of the other bugs[3] in Hugs.
