4038,hash_value(float) collision,dsharlet@…,Daniel James,"the hash_value function for floats has at least one collision that is rather serious:

std::size_t zero = boost::hash_value(0.0f);
std::size_t half = boost::hash_value(0.5f);

both of these have the same hash value. Why not just use reinterpret_cast <> for this hash function?",Bugs,closed,Boost 1.43.0,hash,Boost 1.41.0,Problem,fixed,hash_value collision float,
