Functions
template<typename genType >
GLM_FUNC_DECL int	bitCount (genType v)
	Returns the number of bits set to 1 in the binary representation of value. More...
template<length_t L, typename T , qualifier P>
GLM_FUNC_DECL vec< L, int, P >	bitCount (vec< L, T, P > const &v)
	Returns the number of bits set to 1 in the binary representation of value. More...
template<length_t L, typename T , qualifier P>
GLM_FUNC_DECL vec< L, T, P >	bitfieldExtract (vec< L, T, P > const &Value, int Offset, int Bits)

template<length_t L, typename T , qualifier P>
GLM_FUNC_DECL vec< L, T, P >	bitfieldReverse (vec< L, T, P > const &v)
	Returns the reversal of the bits of value. More...
template<typename genIUType >
GLM_FUNC_DECL int	findLSB (genIUType x)
	Returns the bit number of the least significant bit set to 1 in the binary representation of value. More...
template<length_t L, typename T , qualifier P>
GLM_FUNC_DECL vec< L, int, P >	findLSB (vec< L, T, P > const &v)
	Returns the bit number of the least significant bit set to 1 in the binary representation of value. More...
template<typename genIUType >
GLM_FUNC_DECL int	findMSB (genIUType x)
	Returns the bit number of the most significant bit in the binary representation of value. More...
template<length_t L, typename T , qualifier P>
GLM_FUNC_DECL vec< L, int, P >	findMSB (vec< L, T, P > const &v)
	Returns the bit number of the most significant bit in the binary representation of value. More...
template<length_t L, qualifier P>
GLM_FUNC_DECL void	imulExtended (vec< L, int, P > const &x, vec< L, int, P > const &y, vec< L, int, P > &msb, vec< L, int, P > &lsb)
	Multiplies 32-bit integers x and y, producing a 64-bit result. More...
template<length_t L, qualifier P>
GLM_FUNC_DECL vec< L, uint, P >	uaddCarry (vec< L, uint, P > const &x, vec< L, uint, P > const &y, vec< L, uint, P > &carry)
	Adds 32-bit unsigned integer x and y, returning the sum modulo pow(2, 32). More...
template<length_t L, qualifier P>
GLM_FUNC_DECL void	umulExtended (vec< L, uint, P > const &x, vec< L, uint, P > const &y, vec< L, uint, P > &msb, vec< L, uint, P > &lsb)
	Multiplies 32-bit integers x and y, producing a 64-bit result. More...
template<length_t L, qualifier P>
