[sage-support] Problem with plot3d in VirtualBox

2009-11-14 Thread Michael Madison
I have been running Sage 4.2 from VirtualBox successfully for a while. However, I just tried plot3d and it shuts down Firefox and the work sheet I run it from stops working, meaning I can't reload it. Has anyone else run plot3d from Virtualbox? My computer configurations is: Intel Celeron M 1.5

Well, currently, the ftp server has only root on it so I can upload materials for my lovelies. Then they download via anonymous ftp. I used slackware and proftpd to set up that server eons ago. HTH, A. Jorge Garcia http://calcpage.tripod.com Teacher Professor Applied Mathematics, Physics 

[sage-support] arithmetic in python

2009-11-14 Thread pong
I apologize in advance that this is essentially a question about python instead of sage. When I type 0.6**2 in python, it returns 0.35999 When I do the same in SAGE 0.360 It gives the correct answer. Why so? And can I make python gives the correct answer as well?

Thanks for the suggestion. I understand it now. Just curious, so what exactly does SAGE do when I type 0.6**2 then? I tried a quick search with SAGE tutorial this time, but didn't seem to find what I'm looking for. Thanks in advance On Nov 14, 10:06 am, William Stein wst...@gmail.com wrote:
