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
