I don’t think I ever used atanh, but I always love some floating-point nerdery. These other documents by the same team are fantastic resources: <a href="https://inria.hal.science/hal-04714173v2/document" rel="nofollow">https://inria.hal.science/hal-04714173v2/document</a> for complex values and <a href="https://members.loria.fr/PZimmermann/papers/accuracy.pdf" rel="nofollow">https://members.loria.fr/PZimmermann/papers/accuracy.pdf</a> for real values.<p>Lots of good stuff here: <a href="https://members.loria.fr/PZimmermann/papers/" rel="nofollow">https://members.loria.fr/PZimmermann/papers/</a> .
