This is Python's default behavior. repr uses 17 digits of precision
while str only uses 12. It is covered in the

Another evil example:

It seems that the plot algorithm is somehow deficient in those cases.
In both cases, it's plotting points

Hi Alfredo and Lucio,
Thanks to both of you for your very informative replies and all your
great work on LiveCD's. I can imagine places with minimal hardware
and minimal (or no) network access where these CD's (or USB drive
installations) could be an invaluable help in the study of mathematics
In trying to use the notebook in spanish, there's something
broken with the encoding which prevents using non-ascii characters.
For example, if one changes the title of a worksheet to something with
non-ascii characters, it seems to work at first, but when going back
to the list of worksheets the

Thank you all for your feedback.
I agree that maintaining anoher version of Sage is probably spreading
current resources too thin. I was asking to see if this was indeed the
case. On the other hand, an engineering and physics oriented Sage
could help boost Sage and bring in more resources from

For a while now, I haven't been receiving email notifications of
changes in trac tickets. Has the notification option been turned off?
Can we turn it back on? I notice that it's off by default http://
