What I need is a template version of abs, not the int abs(int) function, to make use of it genericly.

Do you really need a template of it? I can't see why using ADL wouldn't be enough (with a using declaration for std::abs, to catch the overloads for scalars from <cstdlib> and <cmath>).

I certainly use template versions of Max, Min, and AbsoluteValue, because I need them for user-defined classes (that represent real numbers) and not just for built-in types.
