| | | | | | | | zero out into its own check. This change mostly affects ARM processors. They seem to not do well with nest branches whereas x86 do fine. Breaking out this nested if makes no computational difference on x86 but makes a ~5-6% improvement for the ARMv7 tests. Also updates the docs to reflect the new mean error from the function.
