glm::fastLog
GLM_FUNC_DECL vec< L, T, Q > fastLog(vec< L, T, Q > const &x)
Faster than the common exp2 function but less accurate.
glm::fastExp
GLM_FUNC_DECL vec< L, T, Q > fastExp(vec< L, T, Q > const &x)
Faster than the common exp function but less accurate.
glm::fastPow
GLM_FUNC_DECL vec< L, T, Q > fastPow(vec< L, T, Q > const &x)
Faster than the common pow function but less accurate.
glm::fastExp2
GLM_FUNC_DECL vec< L, T, Q > fastExp2(vec< L, T, Q > const &x)
Faster than the common exp2 function but less accurate.
glm::fastLog2
