I think I'm overlooking something very simple, but I'm trying to generate random numbers that are uniform over the open range of various data types. So I wrote this code: template<typename T> struct rand_type_range { typedef boost::numeric::bounds<T> bounds; static T generate() { static boost::uniform_int<T> range(bounds::lowest()+1, bounds::highest()-1); static boost::variate_generator generate(rng, range); return generate(); } }; Using this with anything other than a boost::uint32_t gives lots of warnings, although the results turn out correct. Looking at the warnings it seems the infrastructure is still trying to use boost::uint32_t's for everything, so am I missing something simple? 1>Q:\include\boost\1.39.0\boost/random/uniform_int.hpp(135) : warning C4244: '+=' : conversion from 'unsigned long' to 'unsigned short', possible loss of data 1> Q:\include\boost\1.39.0\boost/random/uniform_int.hpp(64) : see reference to function template instantiation 'unsigned short boost::uniform_int<IntType>::generate<Engine>(Engine &,unsigned short,unsigned short,unsigned short)' being compiled 1> with 1> [ 1> IntType=boost::uint16_t, 1> Engine=boost::random::detail::pass_through_engineboost::int32_t,48271,0,2147483647,399268537 possible loss of data 1> Q:\include\boost\1.39.0\boost/random/uniform_int.hpp(150) : see reference to function template instantiation 'unsigned short boost::uniform_smallint<IntType>::operator ()<Engine>(Engine &)' being compiled 1> with 1> [ 1> IntType=unsigned short, 1> Engine=boost::random::detail::pass_through_engineboost::int32_t,48271,0,2147483647,399268537 link
