Re: [boost] [math] pow redux and observations

I don't remember the following being suggested: --ges template<int N> struct positive_power_increment; template<> struct positive_power_increment<1> { template<typename T> static T result(T pow2, T base) { return pow2 * base; } }; template <> struct positive_power_increment<0> { template<typename T> static T result(T pow2, T base) { return pow2; } }; template<int N> struct positive_power { template <typename T> static T result(T base) { T val = positive_power<N/2>::result(base); return positive_power_increment<N%2>::result(val*val,base); } }; template<> struct positive_power<1> { template <typename T> static T result(T base) { return base; } };
