C++11 constexpr would handle the function case while also working for user defined types. This suggests that the template version is less generic.

Botet Escriba Sent: Sunday, September 25, 2011 7:13 AM To: boost@lists.boost.org Subject: [boost] [Review:Algorithms] About a static clamp function Hi, Sometimes the bound values are know at compile time. Could we ensure that the compiler could optimize the following code auto res = clamp(val, 1, 100); If this is not the case, I was wondering if it is worth adding a static clamp function that has its bounds defined as template parameters. auto res = static_clamp<1,100>(val); Best, Vicente _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
