Hello, First, the function oct does not work properly, it seems.
oct(2345) fails in Sage (but works in Python) oct(int(2345)) works hex(2345) works Irc said it was the preparser. Why would the input of oct be preparsed correctly and not that of hex ? Sage uses notions from abstract algebra. I never use abstract algebra when doing my coding in physics. I guess software like Mathematica kind of guesses the best way to proceed with the input I give. Now, this guess might not be the most appropriate. So I'd be grateful if anyone had some suggestions for a book on abstract algebra that would teach me the practical usage of rings, fields, etc. from a computational point of view ; something like "common computational errors and fallacies corrected by an abstract algebra approach", something that would build upon ideas like "1/3 + 1/10**20 - 1/3" is better done in the the rationals than in the floats. Maybe some book similar to Forman Acton's books that would explicitly use notions of abstract algebra. I had a look at Schaum's Modern Abstract Algebra by Ayres, 2004, but comments on amazon mentioned multiple errors, opacities and out of datedness. Irc suggested wikipedia. Any other suggestion ?
