Yes, there is no math library because I am not qualified to write one
and I didn't see it as important for embedded development so I never sat
down to learn how to do it.

All the libm functions in the code have been contributed by people who
needed them, and that was basically one guy who owned an i386 (also that
processor has the nice property that it implements many libm function as
cpu instructions).

Sorry about that.
