WebAug 1, 2005 · So the quantity by which the Budan–Fourier count exceeds the number of actual roots is explained by the presence of extravirtualroots. The Budan–Fourier count of virtual roots is a useful addition to [5]. It gives a way to obtain approximations of the virtual roots, by dichotomy, merely by evaluation of signs of derivatives.

WebBudan's theorem gives an upper bound for the number of real roots of a real polynomial in a given interval $(a,b)$. This bound is not sharp (see the example in Wikipedia).
