integer exponentiation

[mzimmers]

How do you handle it -- roll your own function, or use something off-the-shelf?

Role your own I suppose. Integers aren't too tricky to handle.

[mzimmers]

Yeah, I suppose you're right...it just still amazes me that C++ doesn't provide a function for this.

Why should it? You rarely need to work with integer types for this kind of math.

That said, there are simple methods for it:

Hope this helps.
