# Get vector length with GLM

I am quite confused over how GLM library is behaving or I am using it improperly.

glm::vec2 testVec(6,-4);

float len = testVec.length();


I get the value 2 with the above code snippet. I believe I am trying to get the length of the vector defined by testVec. You know very well that it is not the correct length of the vector. What am I missing here?

glm::vec2 testVec(6,-4);

The member function of the same name returns the number of components instead (i.e. vec2::length will always yield 2, vec3::length will always yield 3, etc.).
