Detailed Description

Allow the measurement of the accuracy of a function against a reference implementation.

This extension works on floating-point data and provide results in ULP. <glm/gtc/ulp.hpp> need to be included to use these features.

Function Documentation

| GLM_FUNC_DECL uint glm::float_distance | ( | T const & | x, | | | | T const & | y | | | ) | | |
