Accuracy of single precision functions

12

@zimmermann6 has a publication comparing the accuracy of single precision functions across several libms. https://members.loria.fr/PZimmermann/papers/accuracy.pdf The tests are with openlibm 0.4.1, and it would be nice to be able to...

Hello all, I'm not sure whether anyone is interested in this, but I have successfully ported a number of the OpenLibm math routines to [ELKS](https://github.com/jbruchon/elks), an 8086-based Linux kernel and...
