It seems to me that the fpclassify.hpp/sign.hpp functions, that correspond
to the "Classification macros" section of C99, are "core" enough to stand
apart from the rest of the Math library.

We could have a "float" module, the analog of the "integer" module, but for
the built-in floating point types, which would be the natural place for
those functions.

No opinion on that one. It's just a handful of functions anyway. Pretty much
anything will work.
