Where is pow function defined and implemented in C?

Question

I read that the pow(double, double) function is defined in \"math.h\" but I can\'t find its declaration.

Does anybody know where this function declared? And where i

Answer 1

Quite often, an include file such as will include other header files that actually declare the functions you would expect to see in . The idea is that the program gets what it expects when it includes , even if the actual function definitions are in some other header file.

Finding the implementation of a standard library function such as pow() is quite another matter. You will have to dig up the source code to your C standard runtime library and find the implementation in there.
