Subject: [musl] accuracy of mathematical functions
Date: Tue, 03 Aug 2021 10:36:44 +0200	[thread overview]
Message-ID: <> (raw)


I am about to release a new update of the accuracy comparison of mathematical
functions [1]. It will mention Musl 1.2.2, the last release to date. The
following issues are still present in 1.2.2:

* acoshf and sinhf return a finite value instead of NaN (or the converse).
  Fixed by Szabolcs in February, but no new release since then.

* huge maximal errors for j0f, j1f, lgammaf, y0f, y1f

* huge maximal errors for j0, j1, lgamma, y0, y1

* large maximal known error for exp10l (40.1 ulps), expm1l (9.71e3 ulps),
  sinhl (9.71e3 ulps), powl (533 ulps), huge maximal known error for
  lgammal (9.08e19 ulps) and tgammal (3.69e19 ulps)

Best regards,
