Hmm - just when I checked for the authors name I notice, that this article was already posted in december (I must have missed this) and only something was currently edited. Gottfried RE: [MO]: Pade-approximation method for iteration of exp(x)-1 - bo198214 - 02/14/2011 You write in the title exp(x)-1, but it is exp, isnt it? Reminds me a bit of the rational approximation approach by Ansus, though I think he used it rather for the superfunction instead of the fractional iterates.

True - seems my brain lowers its input-separation precision... :-( I'll update the header line. Thanks for the check Gottfried
