Dear all, please review the code I've attached to MATH-849. The improvement in accuracy is great. I also implemented, besides logGamma(x), a new function -- namely Gamma(x). I would like to know if you feel the references to the NSWC library is fair.
Thanks for your advice, Sébastien PS : with this new impl, some tests now fail in GammaDistribution (as expected, this is related to MATH-753). I'm on it.
