[Boost-users] Random Library

Hi, I have a question about the random library. I'm using vc7.1 and I'm getting a warning when I include the random library. The warning I get when I, #include <boost\random.hpp> is: d:\includes\boost_1_31_0\boost\random\linear_congruential.hpp(233) : warning C4244: 'return' : conversion from 'boost::uint64_t' to 'boost::int32_t', possible loss of data When I look at the file, rand48::operator() returns an int32_t, but lcf is defined with uint64_t. Thanks in advance for any help. Andy.
