Aside from long double support, we seem to be missing the following
math functions (and their float equivalents):
Function Description Notes
----------------------------------------------------------------------
exp2(x) 2^x Documented but not implemented
fdim(x, y) |x - y|
fma(x, y, z) x * y + z
fmax(x, y) x > y ? x : y
fmin(x, y) x < y ? x : y
log2(x) log_2(x)
nan(str) NaN The meaning of str is implementation-defined
nearbyint(x) rint(x) Unlike rint(), does not raise an exception
nexttoward(x, y)
nextafter(x, y) The second argument is a long double
remquo(x, y, *q)
remainder(x, y) Stores ((x / y) mod 2n) in *q (n >= 3)
