Forth has a core wordset (basically a library) and a bunch of separate
optional wordsets, each of which is standardized.  Floating point
arithmetic is an optional wordset so it's fine if your implementation
doesn't have it.  But if you do choose to supply floating point
features, the standard says what those features should do, so you don't
have to make it up as you go along.

Maybe C could use a similar approach.
