If you know of any other fits to interesting functions I'd appreciate a
pointer to the work.
Finding high quality, numerically stable, smooth piecewise fits is a
challenge.

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 ste...@arl.army.mil.
