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.pat
ch .  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 [email protected].
