PolyRootsRB finds the roots of a polynomial to any chosen accuracy using Laguerre's Method. The coefficients of the polynomial can be real or complex. PolyRootsRB uses my own multi-precision engine, fp. PolyRootsRB is released with no restrictive license.
Version 1.1 adds the ability to set "Round To Zero" ON or OFF.
Version 1.2 corrects a bug which got incorrect signs for some complex coefficients in an x-based polynomial.
Version 1.3 allows the analysis of some x-based polynomials copied from the internet by PolyRootsRB filtering out spaces, *'s, \'s, and the ASCII for CR and LF for such x-based polynomials.
