## Detailed Description

Non-GLSL types that are used to define precision-based types.

The GLSL language allows the user to define the precision of a particular variable. In OpenGL's GLSL, these precision qualifiers have no effect; they are there for compatibility with OpenGL ES's precision qualifiers, where they do have an effect.

C++ has no language equivalent to precision qualifiers. So GLM provides the next-best thing: a number of typedefs of the Template types that use a particular precision.

None of these types make any guarantees about the actual precision used.
