Expand description

Finds an approximation to a complex root of the given integer polynomial.

This function does not try to be as efficient as possible, but instead tries to avoid (or at least detect) as many numerical problems as possible.

The first return value is an approximation to the root of the polynomial, and the second return value is an upper bound to the distance to the exact root.
