## Detailed Description

Vector types with precision qualifiers which may result in various precision in term of ULPs.

GLSL allows defining qualifiers for particular variables. With OpenGL's GLSL, these qualifiers have no effect; they are there for compatibility, with OpenGL ES's GLSL, these qualifiers do have an effect.

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

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