Not the topic of this thread, but I really think that "NaN in RR" should
return False. RR represents the real numbers and NaN is *not a number*.
Note that Sage

Hello,
In the current beta I have
sage: bool(log(8) == 3*log(2))
False
Why Sage is not able to check this simple relation directly? Hopefully,
sage: bool((log(8) == 3*log(2)).simplify_log())
True
But not very convenient.
Best,
Vincent

I strongly agree with this point of view! Elements belong to some parent,

Note that I wasn't saying anything about Nathann's opinions, and I even
said that some of them were valuable. We could / should debate many things,

The behavior for floating point is governed by IEEE standards, which
dictate +infinity in this case. So I think this is not a bug.

Haha! But eventually one
I don't know you... But I have come to need SMC : I don't use windows !
I was very reluctant to use it because I don't like to work on internet.
But it's such a great application and specially nowadays I can work with
vpython and ivisual ! My wish for so many years and no more windaube ! (lol)

Dear all,
I answer this thread only now as I haven't had much time to read sage-devel
these past days.
First, I must say that I feel very offended my Nathann public implication
that by being part of ODK I "build my career on other people's work".

Actually the idea per se is not so bad but you would use a separate system
like PRESS:
http://dream.inf.ed.ac.uk/software/press/
This would need to be made a Sage package and be interfaced as usual.

Who needs wireless? I thought that was what git was good for ;)
