I have already looked at the gcd algorithm in Ginac, and it would be easy to completely replace it by calls to Singular, so we could completely eliminate the GCD (etc.) code from pynac. In any case, we're using Ginac almost entirely as a foundation for fast basic arithmetic, and for not much else. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
