[sage-support] subtraction with dates?

I'd like to find the number of days between two dates - is there any simple way to do this in Sage. The reason for wanting this is quite funny, but I thought I'd use it to plug Sage! Our car got damaged by a pothole. We made a claim to the council. We finally receiving a letter from their leg

Hi, This is a quick update on the new http://ask.sagemath.org site. 1. There are now 77 registered users. 2. There have been 55 questions asked (with over 90 tags), and all were answered (one is technically unanswered). The top tag categories are "Cython" and "Notebook". 3. The perso

[sage-support] Disabling the "sage: " prompt

Hello, I would like to disable the "sage: " prompt from within Sage. I would like to call Sage from a script (using pipes) and the prompt makes it harder to parse the output. The best approximation that I found was sage.misc.interpreter.set_sage_prompt("") which reduces the prompt to ": " I'm su

[sage-support] Fixed Point arithmetic

Hello, Is there any support in Sage for fixed point arithmetic? That is, computing with real numbers with a fixed number of bits after the decimal point? If it doesn't exist, it probably wouldn't be too hard to implement on top of MPIR. Jeroen. -- To post to this group, send email to sage-sup
