Why isn't `int pow(int base, int exponent)` in the standard C++ libraries?

Question

I feel like I must just be unable to find it. Is there any reason that the C++ pow function does not implement the \"power\" function for anything except

Answer 1

A very simple reason:

5^-2 = 1/25

Everything in the STL library is based on the most accurate, robust stuff imaginable. Sure, the int would return to a zero (from 1/25) but this would be an inaccurate answer.

I agree, it's weird in some cases.
