Sorry about the patch. Attaching it now so it can be considered as submitted.
There is a typo in the XML doc:

Please check that the documentation compiles.
I'm at odds with having the integer version rely on a double pow(), even if it works. I think that there should be a specific integer version which does use integer operations. From stack overflow, the following is suggested:
int ipow(int base, int exp) { int result = 1; while (exp) { if (exp & 1) result *= base; exp >>= 1; base *= base; }
return result; }
The integer version should be when x & y are integers *AND* y >= 0.
if y is a negative integer, the double version should be used.
