Thanks Ralf...yes much better Adding first line...
n = var('n') assume(n,'integer') #solve(n^2-3,n) #solve(n^2 + 2*n + 1,n) solve((n-1)*(n^2+1),n) ..and I have very happy to get only integer roots. But dreamingly, I would like SAGE display (at least) error "deprecated" (more precisely "not implemented" or "not working") for my n = var('n',domain='integer')...it's always better than displaying wrong results To avi : try again and don't despair.. read Boileau :"Hasten slowly, and without losing heart, put your work twenty times upon the anvil." -- You received this message because you are subscribed to the Google Groups "sage-support" group.
