So point must be getting confused by this; indeed, points(map(lambda x:x[0].N(),(z^20-1).roots())[:4], figsize=4, aspect_ratio=1) works fine. > Advice ?

In the meantime, points(map(lambda x:CC(x[0].N()),(z^20-1).roots()), figsize=4, aspect_ratio=1) works nicely, I think. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
