Dear boosters, seems like this code
template< typename T > bool is_nan( const T& v ) { return std::numeric_limits<T>::has_quiet_NaN && (v != v); } does not work correctly on some machines. As far, as I can remember, intervals library also use similar implementation of is_nan. So there should be just the same problem. Respect, Justinas V.D. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
