Because n1692, the paper presented to the C++ Standards Committee in 2004 that I based XInt's interface on, has them there.
Nope, I just looked at the paper, they are free standing functions there. And they are named without the is_ prefix: const int sign( const integer & ); const bool even( const integer & ); const bool odd( const integer & ); const bool getbit( const integer &, unsigned int ); ... BTW there is *no* nan and is_nan in this paper. Please be more precise. Regards, Joachim -- Interval Container Library [Boost.Icl] http://www.joachim-faulhaber.de
