There are certainly formulas for solving polynomials numerically up to
4th degree non-iteratively, but you will almost certainly get better
results using iterative methods.

I must be missing something here. Why not use the analytic formulas for
polynomials below 5th degree? Once you do so, your answer is as precise
as the level of precision you enter for the coefficients.
