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