I was wondering if GiNaC has support for interval arithmetic, and if not, then how to add it (would it just be a new numeric type with it's own rules?) or are there any other packages out there that can be combined with GiNaC?
This would probably not so too easy. There are a number of places where GiNaC does not make the assumption that a given number be real. I don't know how interval arithmetic looks with complex numbers. Frankly speaking, I also don't know how it looks with non-ring operations like the division in the real world where intervals tend to contain 0...
I need symbolic manipulation for my project, but I also need to be able to check very quickly if a given value exists in an interval.
Maybe MPFI <http://www.ens-lyon.fr/~nrevol/nr_software.html> turns out to be interesting for you. Regards -richy. -- Richard B. Kreckel <Richard.Kreckel@GiNaC.DE> <http://www.ginac.de/~kreckel/>
