Re: [sage-support] Output in characteristic 2

The command sage: P. = GF(2)[] is *not* declaring variables x0, x1, etc to be elements in GF(2) but rather *assigns* x0, x1, etc to be generators of a poynomial algebra. sage: P. = GF(2)[] sage: (x0 * x1 + x3 + 1)^2 x0^2*x1^2 + x3^2 + 1 If you want to use elements of GF(2) simply do sage: K =

Try if it works if you use rationals (-48/100) instead of floats (-0.48). On Monday, February 3, 2020 at 8:48:34 AM UTC-5, Murad Tukan wrote: > > Dear all, > > Computer info: > CPU: i7-6500U @ 2.50GHZ > Memory: 16.0GB > > Sage information: SageMath 9.0 (Windows, installed using the .exe file), >

This actually works fine. Why when running with 2 digit floating points, the code doesn't run? Is there any way to make it work with floats?? On Monday, 3 February 2020 16:15:57 UTC+2, Matthias Koeppe wrote: > > Try if it works if you use rationals (-48/100) instead of floats (-0.48). > > On Mond

I typically use Windows, but today I was trying to install Sage on the Mac in one of my classrooms. It turns out to be running OSX 10.13.6, and the only binaries I could find were version 8.7. I managed to download and install those. It runs in a terminal window. The instructions say to type notebo
