For C-language programmers a new Free Software tool is
available to compute length of ellipse, arcs of ellipse,
and more data.
It's the "Conic Library", which has been released under GPL
license on the Web location: http://www.outisonoma.net
in the first beta version: conic-0.1b.tar.gz
few days ago.
This first version can compute ellipses with eccentricity
ranging from 0 to sqrt(0.5).
On the above range, the quarter length returned from the
"Conic Library" is the same as returned from the classic
exact Series of Gauss-Kummer, up to 14 digits.
The above range should be extended in successive versions.
