\subsection{Where's the documentation?}
The Doxygen-generated documentation includes a complete list of all extensions available, and can be found right \href{http://glm.g-truc.net/html/index.html}{here}.

\subsection{Visual C++ gives me lots of warnings on on warning level \texttt{/W4}.}
You should not have any warnings, even in \verb|/W4| mode. However, if you expect such level for you code, then you should ask for the same level to the compiler by at least disabling the Visual C++ language extensions (\verb|/Za|) which generates warnings when used. If these extensions are enabled, then GLM will take advantage of them and the compiler will generate warnings.

\subsection{Why are some GLM functions vulnerable to division by zero?}
Such behavior is the result of a domain error that follows the precedent set by C and C++. For example, it's a domain error to pass a null vector (all zeroes) to glm::normalize, or even to pass a negative number into \verb|std::sqrt|.
Such behavior follows the precedent set by C and C++'s standard library, in that it's treated as a domain error. For example, it's a domain error to pass a null vector (all zeroes) to \verb|glm::normalize|, or to pass a negative number into \verb|std::sqrt|.
