Does the GLM library for OpenGL not have a magnitude function?

Question

I'm new to using the GLM library, but it appears it does not have a magnitude function. Is this correct? If so, what is the reasoning?

If you just need to compare magnitudes, you may want to use `glm::length2()` from the `gtx/norm.hpp` extension, as it avoids the expensive `sqrt`. It is essentially equivalent to `glm::dot(v,v)`. — bcrist, Nov 08 '13 at 21:14

genType::value_type glm::length( genType const & x )

Returns the length of x, i.e., sqrt(x * x).

T glm::length2( vecType< T, P > const& x )

Returns the squared length of x.
