Wrong answers in the specific case

[batist73]

Hello!
I've tried next coefficient in the program: 1, -2, -1, 1.
So it's the equation x^3 - 2 * x^2 - x + 1 = 0.
And I've got the answers 2.1776150834928703, -2.0236846915106783, -0.15393039198219122.
But the correct answers are -0.80194, 0.55496, 2.2470 (checked in the Wolfram Alpha).
I hope, that this will help you.

Yes, you should merge this.
I've tested this merge request massively, it gives the same result as math.polynomialRoot (from project mathjs) but very very faster

Thanks for your works, simple fast module like this is why I need
