Re: [sage-support] Re: Stange behavior with QQbar[z]

Concerning representation of algebraic numbers, it is printed as an exact rational if and only if it is stored as an exact rational. It will be if the method exactify has been called on the underlying representation of the number. Here is a simple example that shows the difference sage: a = QQbar(

Thanks for you reply. I know import igraph works in sage. But I have installed two different packages: igraph and python_igraph. And what I want to do is import them in python. 在 2016年11月7日星期一 UTC+1下午2:29:58，Jeroen Demeyer写道： > > On 2016-11-07 13:52, Eden Harder wrote: > > I installed sagemath

[sage-support] Stange behavior with QQbar[z]

Something strange (at least for me). I am computing with polynomials in QQbar[z]. So I do: sage: P.=QQbar[] And I define 2 polynomials N and D. Coefficients of N and D are all real, algebraic numbers (say like QQbar(sqrt(3))) and I consider the rational fraction R=N/D sage: R.parent() Fraction

Hi The missing file is a relatively new file: https://git.sagemath.org/sage.git/commit/?id=8ccd4404feb6a610bc0b2f816ae74f38178d065d I had not noticed the new file, and did not include it in sagemath-upstream-binary-full. (Also Makefile.in and README.txt). I've now added that to our debian install
