Re: [sage-devel] [patch-2.7.6] Error downloading tarball of patch

It seems that the most recent version of patch in homebrew no longer provides automatic access to a binary "patch" (which I think it used to do); instead it says If you need to use it as "patch", you can add a "gnubin" directory to your PATH from your bashrc like: PATH="/opt/hom

See the documentation on QQbar . While I'm sure there are related bugs, I agree with Nils that in this case it's working as intended. If you need a very small nonzero number, the system will compute with enough precisi

Just trying to show that real roots can be easily computed, not relying on the bugs in roots over QQbar. I don't see way to control the precision in the spectrum. Who decides that small algebraic number is real, is it user's responsibility, discarding visual non-zero? e-60 is zero is e-58 zero or j
