glm::highestBitValue
GLM_FUNC_DECL vec< L, T, Q > highestBitValue(vec< L, T, Q > const &value)
Find the highest bit set to 1 in a integer variable and return its value.
glm::powerOfTwoBelow
GLM_DEPRECATED GLM_FUNC_DECL vec< L, T, Q > powerOfTwoBelow(vec< L, T, Q > const &value)
Return the power of two number which value is just lower the input value.
glm::powerOfTwoAbove
GLM_DEPRECATED GLM_FUNC_DECL vec< L, T, Q > powerOfTwoAbove(vec< L, T, Q > const &value)
Return the power of two number which value is just higher the input value.
glm::powerOfTwoNearest
GLM_DEPRECATED GLM_FUNC_DECL vec< L, T, Q > powerOfTwoNearest(vec< L, T, Q > const &value)
Return the power of two number which value is the closet to the input value.
