How exactly?

I don't know who is "we" (Atmel? :-) ) but


<math.h>:
extern double pow(double __x, double __y) __ATTR_CONST__;


C99 6.9.1#10
On entry to the function, the size expressions of each variably modified
parameter are
evaluated and the value of each argument expression is converted to the
type of the
corresponding parameter as if by assignment.
