Martin Hořeňovský 7f931d6df4 Add tests for scaled ULP distance between +/- FLT/DBL_MAX 2024-01-14 21:15:02 +01:00
Martin Hořeňovský d139b4ff7c Add implementation of helpers for uniform float distribution 
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].

Martin Hořeňovský 3d1cf95b32 Fix ulp distance calculation for numbers with different signs 
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
