8275	conversion_traits::super/subtype incorrect for UDT's	John Maddock	Douglas Gregor	"The following static assertion fails:

{{{
#include <boost/numeric/conversion/conversion_traits.hpp>
#include <boost/multiprecision/cpp_dec_float.hpp>

   using namespace boost::multiprecision;
   BOOST_STATIC_ASSERT(boost::numeric::convdetail::get_is_subranged<cpp_dec_float_50, cpp_dec_float_100>::type::value);

}}}

Which causes all sorts of other failures in clients of this class - it looks like UDT conversions are treated as always non-narrowing (?) where as use of numeric_limits would quickly reveal otherwise."	Bugs	new	To Be Determined	numeric	Boost Development Trunk	Problem
