SDF implements url=http://en.wikipedia.org/wiki/Jenkins%E2%80%93Traub_algorithmJenkins-Traub/url algorithm for polynom root finding.

Polynom degree is theoretically infinite, from practical reasons limited to 100.

list
*Coefs - Zero-based list of coefficients. Sorted from the lowest to the highest (X0, X1, X2, .. Xn)/*:m
*Result - Real polynom roots, sorted from lowest to highest./*:m/list:u

object X = Math.GetPolynomRoots(object Coefs)

buSyntax:/u/b
object X = Math.GetPolynomRoots(double X0, double X1, double X2, double X3, double X4, double X5, double X6)

size=150Complex roots of the polynom/size

Polynom root finder can return also complex roots of the polynom.
