glm::imulExtended
GLM_FUNC_DECL void imulExtended(vecType< int, P > const &x, vecType< int, P > const &y, vecType< int, P > &msb, vecType< int, P > &lsb)
Multiplies 32-bit integers x and y, producing a 64-bit result.
glm::bitfieldInsert
GLM_FUNC_DECL vecType< T, P > bitfieldInsert(vecType< T, P > const &Base, vecType< T, P > const &Insert, int Offset, int Bits)
Returns the insertion the bits least-significant bits of insert into base.
glm::usubBorrow
GLM_FUNC_DECL vecType< uint, P > usubBorrow(vecType< uint, P > const &x, vecType< uint, P > const &y, vecType< uint, P > &borrow)
Subtracts the 32-bit unsigned integer y from x, returning the difference if non-negative, or pow(2, 32) plus the difference otherwise.
glm::findLSB
GLM_FUNC_DECL vecType< int, P > findLSB(vecType< T, P > const &v)
Returns the bit number of the least significant bit set to 1 in the binary representation of value...
glm::bitCount
GLM_FUNC_DECL vecType< int, P > bitCount(vecType< T, P > const &v)
Returns the number of bits set to 1 in the binary representation of value.
glm::uaddCarry
GLM_FUNC_DECL vecType< uint, P > uaddCarry(vecType< uint, P > const &x, vecType< uint, P > const &y, vecType< uint, P > &carry)
Adds 32-bit unsigned integer x and y, returning the sum modulo pow(2, 32).
glm::bitfieldExtract
GLM_FUNC_DECL vecType< T, P > bitfieldExtract(vecType< T, P > const &Value, int Offset, int Bits)
Extracts bits [offset, offset + bits - 1] from value, returning them in the least significant bits of...
glm::bitfieldReverse
GLM_FUNC_DECL vecType< T, P > bitfieldReverse(vecType< T, P > const &v)
Returns the reversal of the bits of value.
