Comment #8 on issue 3266 by [email protected]: Numeric issues in hyperbolic functions
http://code.google.com/p/v8/issues/detail?id=3266

Re #5: Actually, I looked at the hyperbolics in fdlibm more closely. They are, for the most part, relatively simple, but they also assume that you have accurate log, exp, log1p, and expm1. log1p is taken care of now. I hope you can get expm1 done. We already know exp is not accurate (https://code.google.com/p/v8/issues/detail?id=3468). I don't know anything about the accuracy of log, but I haven't found any issues with it.

So if we can get accurate exp (note that 3468 was closed as WAI) and expm1, and verify log is accurate, we can have the hyperbolics fixed.
