    Description

      From the two benchmarks we currently have in "FastMathTestPerfomance", we have that the following functions are much slower in "FastMath" than in either "Math" or "StrictMath" (the performance loss, for each of the benchmarks, is given in parentheses):

      • log10 (46%, 36%)
      • log1p (68%, 112%)
      • tan (11%, 61%)
      • atan (26%, 125%)
      • atan2 (44%, 40%)
