Description

I am about to release a new update of the accuracy comparison of mathematical functions. It will be with Openlibm 0.7.5, the last release. The previous update (with Openlibm 0.7.4) is available here: https://members.loria.fr/PZimmermann/papers/accuracy.pdf. For double precision, in 0.7.5, there is still a large maximal error for pow (636 ulps) and tgamma (1.03e3 ulps) and huge errors for j0,j1,y0,y1 and lgamma. All other functions have a maximal known error less than 4.04 ulps.
