frexp takes a pointer as the second argument. I'd have to think more
about frexp and ldexp to make myself sure that passing floats to the
double function actually give the results you'd get from frexpf... but
I guess that'd work?
Similar concerns about ldexp, but I guess we've been doing it for years.
