I have to open a similar one. The support I added for erf is losing a lot of precision due to (2/sqrt(pi)). In case of Float64 there is no real difference, but since this package supports BigFloats too I think it makes sense to rely on IrrationalConstants for sqrtpi or similar, in order to not lose precision.
