finding the real roots of a polynomial with real coefficients is a problem that has received much attention since the beginning of 19th century, and is still an active domain of research. most root-finding algorithms can find some real roots, but cannot certify having found all the roots. methods for finding all complex roots, such as aberth method can provide the real roots. however, because of the numerical instability of polynomials (see wilkinson's polynomial), they may need arbitrary-precision arithmetic for deciding which roots are real. moreover, they compute all complex roots when only few are real.
