Ronald S. Bultje a1245d5ca1 mathematics: Don't use division by zero in NAN/INFINITY macros ...

Some compilers, MSVC among them, don't recognize the divisions by
zero as meaning infinity/nan.

These macros should, according to the standard, expand to constant
expressions, but this shouldn't matter for our usage.
