glm::umulExtended
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::uaddCarry
GLM_FUNC_DECL vec< L, uint, Q > uaddCarry(vec< L, uint, Q > const &x, vec< L, uint, Q > const &y, vec< L, uint, Q > &carry)
Adds 32-bit unsigned integer x and y, returning the sum modulo pow(2, 32).
glm::bitfieldExtract
GLM_FUNC_DECL vec< L, T, Q > bitfieldExtract(vec< L, T, Q > const &Value, int Offset, int Bits)
Extracts bits [offset, offset + bits - 1] from value, returning them in the least significant bits of...
glm::bitCount
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::bitfieldReverse
GLM_FUNC_DECL vec< L, T, Q > bitfieldReverse(vec< L, T, Q > const &v)
Returns the reversal of the bits of value.
