[sage-support] Apostrophe in docstring?

Hello support, I came across some very strange behavior recently regarding docstrings in functions. In the notebook in 3.2.alpha0 and 3.0.6, putting an apostrophe in the docstring causes various bugs. It doesn't have to be in any particular spot, as far as I can tell; in fact, it took a long ti

[sage-support] Re: Groebner basis, Ideal dimension and Variety

I have to deal with this a lot, and I've gotten used to it but it annoys me. More support for specialization would be great. I am not that good with the guts of the polynomial ring code and singular or I would have dealt with it already. I would be happy to review patches related to this. -M.

Hi Robert, thanks again, and sorry, my question was not well posed, fortunately (as a mathematician) I know what an isomorphism is :-), when I asked what does this exactly mean I actually wanted to know if in the cases 'sqrt(5. + RDF(5))' and 'sqrt(RDF(5) + 5.)' computation is performed by two di

[sage-support] Groebner basis, Ideal dimension and Variety

Hello, I have a system of 11 quadratic equations over GF(2) in 8 variables. I compute it's groebner basis. The ideal generated by it has dimension 0 so I compute its variety. It results in 16 solutions (16 possible sets of values for the 8 variables). I take one of the solutions and then i replac

Hi Robert, thanks for your fast answer, just one more question, > RDF and RealField(35) are canonically isomorphic, what does that mean exactly, as far is I know, sage uses the 'gsl' for computations with 'RDF', and computations with 'RR' are done through 'mpfr', so if I write for example 'sqrt(
