glm::fastLn
T fastLn(const T &x)
Faster than the common ln function but less accurate.
glm::fastLog
T fastLog(const T &x)
Faster than the common log function but less accurate.
glm::fastExp
T fastExp(const T &x)
Faster than the common exp function but less accurate.
glm::fastExp2
T fastExp2(const T &x)
Faster than the common exp2 function but less accurate.
glm::fastPow
genType fastPow(genType const &x, genType const &y)
Faster than the common pow function but less accurate.
glm::fastLog2
T fastLog2(const T &x)
Faster than the common log2 function but less accurate.
