GLM_FUNC_DECL void umulExtended(vec< L, uint, Q > const &x, vec< L, uint, Q > const &y, vec< L, uint, Q > &msb, vec< L, uint, Q > &lsb)
Multiplies 32-bit integers x and y, producing a 64-bit result.
GLM_FUNC_DECL vec< L, int, Q > bitCount(vec< L, T, Q > const &v)
Returns the number of bits set to 1 in the binary representation of value.
GLM_FUNC_DECL vec< L, uint, Q > usubBorrow(vec< L, uint, Q > const &x, vec< L, uint, Q > const &y, vec< L, uint, Q > &borrow)
Subtracts the 32-bit unsigned integer y from x, returning the difference if non-negative, or pow(2, 32) plus the difference otherwise.
