## Detailed Description

Include <glm/gtc/ulp.hpp> to use the features of this extension.

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.

## ◆ float_distance() [1/2]

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

Return the distance in the number of ULP between 2 scalars.

## ◆ float_distance() [2/2]

GLM_FUNC_DECL vec<2, uint, Q> glm::float_distance | ( | vec< 2, T, Q > const & | x,
|  | vec< 2, T, Q > const & | y
| ) |  |

Return the distance in the number of ULP between 2 vectors.
