Ah, thanks for a confirmation...
I am interested in a resolution here, which I would like to implement in a function I wrote as a more general iround; I call it round_cast():
<code> template < class R, class T, class Policy > inline R round_cast( T const& x, Policy const& pol ) { BOOST_MATH_STD_USING T r = boost::math::round(x,pol); if( r > boost::integer_traits<R>::**const_max || r < boost::integer_traits<R>::**const_min ) return static_cast<R>( boost::math::policies::raise_** rounding_error( "cz::ar::round_cast<target_**type,%1%>(%1%)", 0, x, pol ) ); return static_cast<R>(r); }
template < class R, class T > inline R round_cast( T const& x ) { return round_cast<R>( x, boost::math::policies::policy<**>() ); } </code>
Isn't that more or less the same as: http://www.boost.org/doc/libs/** 1_47_0/libs/numeric/**conversion/doc/html/boost_** numericconversion/improved_**numeric_cast__.html<http://www.boost.org/doc/libs/1_47_0/libs/numeric/conversion/doc/html/boost_numericconversion/improved_numeric_cast__.html>
John.
I thought that was only for checking range. Or do you mean round(), and then numeric_cast<>() instead of checking range manually in round_cast<>()? Regards Kris
