I was tickled to find mention of my exponential integral (E1(x)) fitting algorithm at http://www.axiom-developer.org/axiom-website/patches/20080119.01.tpd.patch . As noted there, the accuracy of my published fit is only 4 decimal places. Years ago, I extended that original fit to greater precision (with more parameters of course), if it is of use to anyone, though I have not published the extensions. I do not subscribe to your maillist, but am happy to provide the fits, should you provide your request to me at address@hidden
