Comment (by vdelecroix):
Hi,
Did you completely avoid the power series ring? We should provide more
methods to polynomial like:
- `inverse_series(self, prec, as_polynomial=False)`: return the inverse
series and if `as_polynomial` is true returns it as a polynomial
As FLINT has some native implementation, we should use it where it makes
sense. But this should be done in another ticket.
In all your code, you know in advance the precision needed. Right?
Vincent
