Detailed Description

Allow to perform bit operations on integer values.

<glm/gtx/bit.hpp> need to be included to use these functionalities.

genType glm::bitRevert

(

genType const &

value

)

Revert all bits of any integer based type.

		std::size_t	Shift
	)

Rotate all bits to the left.

genType glm::bitRotateRight	(	genType const &	In,
		std::size_t	Shift
	)

Rotate all bits to the right.

		int const &	FromBit,
		int const &	ToBit
	)

Set to 0 a range of bits.

genType glm::powerOfTwoNearest

(

genType const &

value

)
