The critical points are the inequalities and log() in dup_root_upper_bound and is_negative() in dup_sign_variations. Making them work for algebraic numbers is non-trivial. Otherwise the code for root isolation could be used as such except for relaxing the checks for QQ or ZZ. -- You received this message because you are subscribed to the Google Groups "sympy" group.
