OK, can you file a feature request at svn.boost.org so I don't forget this?
Thanks, John.
Done, Ticket #6047 - about round_cast().
Would you like a ticket for the following round_to as well? template < class T > T round_to( const T& x, const T& order ) { return round( x / order ) * order; }
I'm not sure about that one, if "order" is anything other than a power of T's radix then the result will be rounded - ie the result will not necessarily actually be a true multiple of "order"?
I'm still not sure if: can r > boost::integer_traits<R>::const_max be true, and still static_cast<R>(r) == boost::integer_traits<R>::const_max?
Good question, I believe that can be the case if *r has not been rounded*, for example if r == boost::integer_traits<R>::const_max + 0.1. HTH, John.
