title: Why isn't `int pow(int base, int exponent)` in the standard C++ libraries?
body: <p>I feel like I must just be unable to find it. Is there any reason that the C++ <code>pow</code> function does not implement the "power" function for anything except <code>float</code>s and <code>double</code>s?</p>
  
  <p>I know the implementation is trivial, I just feel like I'm doing work that should be in a standard library. A robust power function (i.e. handles overflow in some consistent, explicit way) is not fun to write.</p>
