Okay, this looks like a bug to me: ---------------------------------------------------------------------- | Sage Version 4.1.1, Release Date: 2009-08-14 | | Type notebook() for the GUI, and license() for information. | ---------------------------------------------------------------------- sage: I I sage: R.<I> = ZZ[sqrt(-1)] sage: I 1 sage: I^2 1 Why is I equal to 1 all of a sudden? Same problem here: sage: reset() sage: R.<a> = ZZ[sqrt(-5)] sage: a 1 sage: R.1 a sage: R.1 == a False sage: (R.1)^2 -5 sage: R.inject_variables() Defining a sage: a 1 Ouch. -- John --~--~---------~--~----~------------~-------~--~----~ 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 -~----------~----~----~----~------~----~------~--~---
