Detailed Description

Allow to perform bit operations on integer values.

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

Function Documentation

template<typename genType >
GLM_DEPRECATED genType glm::bitRevert ( genType const &  value)

Revert all bits of any integer based type.

template<typename genType >
genType glm::bitRotateLeft ( genType const &  In,
std::size_t  Shift 
)

Rotate all bits to the left.

GLM_GTX_bit
template<typename genType >
genType glm::powerOfTwoAbove ( genType const &  value)

Return the power of two number which value is just higher the input value.

See also
