Phoenix	A slightly related snippet I wrote a while ago, for expressing binary constants in C++ using template metaprogramming. The benefit of doing it this way is that it all happens during compile-time. template <long long n> struct const_bin { enum { value2 = ((n&1) + const_bin<n/10>::value2) << 1, value = value2 >> 1 }; }; template <> struct const_bin<0> { enum { value2 = 0, value = 0 }; }; // Example usage std::cout << const_bin<110111001>::value << std::endl; --v I don't think it's terribly purposeful, apart from being a cool way of doing it. \|edit\| Oh, and by the way, I will never touch anything licensed under GPL. Public domain FTW! \|edit\| \|edit\| And does this really qualify as a showcase? \|edit\|

cthug	It probably should have been a code snippet but meh, Phoenix it can be public domain, GPL is just the standard header for geany which I use with freebasic.
