Is it clear that 0.0 and -0.0 should be the same in the sense of EQUAL?
Clearly they are the same in the sense of =, and -0.0 is not even
negative, because (< -0.0 0.0) is false by the IEEE rules, as SRFI-77
points out.
But as things now stand, there is no simple way to distinguish them.
They aren't printed differently either, at least not on Cygwin.
