My last post on this topic is now nearly 5 months time ago: http://groups.google.com/group/sage-devel/browse_thread/thread/49069f5090e0f4b9/eaabced82d61573b I didnt get any reply to the formal powerseries code I proposed.
The code had 100% coverage and I put quite some effort into making it picklable. Now I made some minor adaptions to make it work with sage 4.1.1. So here is the current code proposed to be included into sage.rings: http://github.com/bo198214/hyperops/raw/94453bf49e30a55addae6d654cc6f46b8121718d/formal_powerseries.py --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
