Fix Version/s: 1.2
I see no reason not to apply this patch for 1.2.
> Special functions not very accurate

> Key: MATH-166

> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 1.1
> Reporter: Lukas Theussl
> Priority: Minor
> Fix For: 1.2

>
> The Gamma and Beta functions return values in double precision but the
> default epsilon is set to 10e-9. I think that the default should be set to
> the highest possible accuracy, as this is what I'd expect to be returned by a
> double precision routine. Note that the erf function already uses a call to
> Gamma.regularizedGammaP with an epsilon of 1.0e-15.
