When you give this program an approximation to a real number, it will do its best to decide what that number `really' is--in essence, this is a greatly expanded online version of the Dictionary of Real Numbers, mentioned above. For example, the ISC describes as the `lemniscate number'. Simon Plouffe is currently working on this program here at the Centre.
gfun
the Generating Function Package by Salvy et al [4].
This Maple package from the share
library contains functions
for manipulating sequences, linear recurrences, differential equations,
and generating functions of various types. Simon Plouffe and F. Bergeron had
some input into this package, as well.numapprox[pade]
(formerly convert/ratpoly
) in Maple.
This utility uses clever algorithms to convert power series into Padé
approximants.
