Actually, the math functions will change quite a lot; each function will come in
three flavors: float, double, and long double.  I expect that the "float" versions
could easily be derived from the "double" functions currently implemented, but the
"long double" functions will require a lot of new work.  There will also be new
functions, including cbrt, erf, erfc, lgamma, tgamma, fmin, fmax, etc.
Furthermore, most of the transcendental functions will have complex versions,
though the draft standard currently says that an implementation is not required to
support complex arithmetic.  gcc already supports complex arithmetic in a
nonstandard way, so that capability will almost certainly be standardized and
retained.
