Pre-pynac, all floating point numbers that were part of a symbolic expression were 53-bit. Now that they can be arbitrary precision (they are in fact wrapped Sage RealNumbers) the number of digits printed gives an indication of how many digits of precision are known. - Robert --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
