Subject: Accuracy of Mathematical Functions in Single, Double, and Quadruple Precision
Date: Fri, 04 Dec 2020 17:18:31 +0100 [thread overview]
Message-ID: <mwsg8lbl48.fsf@tomate.loria.fr> (raw)
Hi,
I have published a new version of my note, including results for double and
quadruple precision, and also for bivariate functions (atan2, hypot, pow):
https://homepages.loria.fr/PZimmermann/papers/#accuracy
Apart from the Bessel functions for which Newlib has large errors (like other
libraries except the Intel Math Library), this note shows large errors in
Newlib:
* for the binary32 lgamma (7.50e6 ulps), tgamma (239 ulps)
and pow (169 ulps) functions
* for the binary64 lgamma and tgamma functions
Best regards,
Paul Zimmermann
