catch3/src/catch2/internal/catch_floating_point_helpers.hpp, branch v3.5.2 Progmasoft Catch3: an independently maintained C++17 test framework with a parallel runner, property checks, snapshots and structured results. Add implementation of helpers for uniform float distribution 2023-12-10T17:44:10+00:00 Martin Hořeňovský 2023-11-19T20:00:53+00:00 d139b4ff7cd8823923e8616e8fef954e09e46322 Specifically we add * `gamma(a, b)`, which returns the magnitude of largest 1-ULP step in range [a, b]. * `count_equidistant_float(a, b, distance)`, which returns the number of equi-distant floats in range [a, b].

Add Wfloat-equal to default-enabled warnings 2022-05-14T13:47:20+00:00 Martin Hořeňovský 2022-05-14T13:37:39+00:00 fc3d11b1d1090a5bcbcc9e410a460f9bf6a1f474 This is kinda messy, because there is no good way to signal to the compiler that some code uses direct comparison of floating point numbers intentionally, so instead we have to use diagnostic pragmas. We also have to over-suppress the test files, because Clang (and possibly GCC) still issue warnings from template instantiation even if the instantion site is under warning suppression, so the template definition has to be under warning suppression as well. Closes #2406

Fix ulp distance calculation for numbers with different signs 2021-07-27T19:04:41+00:00 Martin Hořeňovský 2021-07-26T20:01:04+00:00 3d1cf95b3247e962ab7ae926b5547c64738a13d9 This is a simplification of the fix proposed in #2152, with the critical function split out so that it can be tested directly, without having to go through the ULP matcher. Closes #2152
