budanFourierBound(f, a, b)
budanFourierBound(f)
This computes the bound from the Budan-Fourier Theorem for the number of real roots in the interval (a,b], counted with multiplicity, of a univariate polynomial f with rational coefficients. It assumes an unspecified interval is $(-\infty, \infty)$. Note that ring f is allowed to be multivariate.

We also provide examples when the interval includes $-\infty$ or $\infty$.
