This is a pretty nice introduction, and makes me want to return to my side project where I used to play with these approximations but for SIMD math: https://github.com/boulos/syrah/blob/master/src/include/syrah/FixedVectorMath.h https://github.com/boulos/syrah/blob/master/src/include/syra... . I hope in a later post he mentions Sollya (http://sollya.gforge.inria.fr http://sollya.gforge.inria.fr), I found it invaluable for playing around with different precision vs speed.
