Hi,

Well, yeah, but that algorithm is not as good as the one in
~kig/misc/kignumerics.cpp, because it uses the direct algebraic
formula, and not the numeric approximation process that Maurizio was
talking about ( he's a professor in numerical analysis, the science
that handles these things, you know :) )...

cheers
