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.
