glm::findMSB
GLM_FUNC_DECL vec< L, int, Q > findMSB(vec< L, T, Q > const &v)
Returns the bit number of the most significant bit in the binary representation of value...
glm::bitfieldReverse
GLM_FUNC_DECL vec< L, T, Q > bitfieldReverse(vec< L, T, Q > const &v)
Returns the reversal of the bits of value.
glm::imulExtended
GLM_FUNC_DECL void imulExtended(vec< L, int, Q > const &x, vec< L, int, Q > const &y, vec< L, int, Q > &msb, vec< L, int, Q > &lsb)
Multiplies 32-bit integers x and y, producing a 64-bit result.

glm::findLSB
GLM_FUNC_DECL vec< L, int, Q > findLSB(vec< L, T, Q > const &v)
Returns the bit number of the least significant bit set to 1 in the binary representation of value...
qualifier.hpp
Core features
glm::bitCount
GLM_FUNC_DECL vec< L, int, Q > bitCount(vec< L, T, Q > const &v)
Returns the number of bits set to 1 in the binary representation of value.
glm::bitfieldInsert
GLM_FUNC_DECL vec< L, T, Q > bitfieldInsert(vec< L, T, Q > const &Base, vec< L, T, Q > const &Insert, int Offset, int Bits)
Returns the insertion the bits least-significant bits of insert into base.
glm::bitfieldExtract
