In my opinion, the self-made version in my initial post is probably superior than yours. :-P which is repeated as follows: #include <boost/utility/value_init.hpp> // my abs function // it works not only for POD types, but also for // user types that are default constructible and // support operator<() and unary operator-() template<class T> T abs(const T & x) { static boost::value_initialized<T> zero; return (x < zero? -x : x); } Max ----- Original Message ----- From: Deane Yang <deane.yang@yahoo.com> To: boost-users@lists.boost.org Subject: Re: [Boost-users] [STL] Is there a std::abs<>() function? (Max) Date: 2008-12-25 18:09:26 I just made up my own naive version. Improvements would be welcome: template<typename T> inline T AbsoluteValue(const T& x) { if (x < T(0)) { return -x; } else { return x; } } Max wrote:

seconded.

But could you tell me where I can find the temple version of AbsoluteValue function you mentioned?

Thanks B/Rgds Max
