It can if certain unit-testing modules are installed. The function that I would like to use does not depend on these modules itself, but nonetheless the import fails because of other statements in the same .py file. Anyway, the use of this function supposes the presence of reference images. I beli

It seems to me that the assumption system is a better place to put all this. I may be wrong but I was left with the impression that it is meant to replace all the is_something stuff. On 18 February 2012 07:37, Nathan Alison wrote: > It would be nice if we could have variables take an interval as

Interval arithmetic seems to be more powerful than either of the current assumptions systems in the case of real variables. I've heard people mention this topic on the listhost before. Is there any past attempt/knowledge on this subject? On Sat, Feb 18, 2012 at 9:51 AM, krastanov.ste...@gmail.com

My hopes are that the new assumptions will be able to handle interval arithmetic, or actually any kind of set arithmetic. Trying to get the old assumptions to do it would be unfruitful and a waste of time, since the design doesn't really allow for it at all. My vision is that we should be able to

Hi. I didn't find any apps called "iPython" in the iOS app store. Perhaps this is what is now called "Python for iOS" (this even shows "import sympy" in one of the screenshots, which is cool). I don't know if you want to mention it, but if you jailbreak iOS, installing SymPy is really easy (just
