Hi
I would like to work with sets that are real intervals or combinations of them : mainly intersection and union. Example : [0,1] intersection with [0.5 , pi] Using the Sage Reference Manual 4.1.1, I was able to do that : sage:A=Set(RealField()) sage: sqrt(2) in A True So it is possible to consider parts of R as sets. How can I build an interval ? Have a good day Laurent Claessens PS : I send this message by email on December, 4. Since I did not even saw my message appearing, I decided to repost it from the GoogleGroup online interface. I'm wrong in doing that ? -- 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 URL: http://www.sagemath.org
