\section{Known Issues}
This section reports the divergences of GLM with GLSL.
This section reports GLSL features that GLM can't accurately emulate due to language restrictions.
\subsection{The \texttt{not} Function}
The GLSL keyword \verb|not| is also a keyword in C++. To prevent name collisions, ensure cross compiler support and a high API consistency, the GLSL \verb|not| function has been implemented with the name \verb|not_| (note the underscore).
The GLSL function \verb|not| is a keyword in C++. To prevent name collisions and ensure a consistent API, the name \verb|not_| (note the underscore) is used instead.
\subsection{Precision Qualifiers}
GLM supports GLSL precision qualifiers through prefixes instead of qualifiers. For example, additionally to \verb|vec4|, GLM exposes \verb|lowp_vec4|, \verb|mediump_vec4| and \verb|highp_vec4| types.
GLM supports GLSL precision qualifiers through prefixes instead of qualifiers. For example, GLM exposes \verb|lowp_vec4|, \verb|mediump_vec4| and \verb|highp_vec4| as variations of \verb|vec4|.
Similarly to GLSL, GLM precision qualifiers are used to handle trade-off between performances and precision of operations in term of ULPs.
By default, all the types use high precision.
As in GLSL, GLM precision qualifiers are used to exchange precision for performance. By default, all types use high precision.

The syntax for default precision specifications in GLM differs from that in GLSL; for more information, see section \ref{Default Precision}.
