maya 038de09f8a compare to zero, instead of using signbit, and be more specific in comment.
-0.0 > 0 is also false. no functional change.

while this is mostly a change to be consistent in style (the rest of the
comparisons aren't done with signbit), it is also a micro-optimization.

with our default compile flags, calls to copysign are libm calls (and a
whole function call!!). this generates more efficient code.
