GLM_FUNC_DECL int floatDistance(float x, float y)
Return the distance in the number of ULP between 2 single-precision floating-point scalars.
GLM_FUNC_DECL genType prevFloat(genType x)
Return the previous ULP value(s) before the input value(s).
GLM_FUNC_DECL genType nextFloat(genType x)
Return the next ULP value(s) after the input value(s).
