numberOfRealRoots

Number of distinct real roots of a univariate polynomial.

Computation of resultant, subresultants, greatest common divisor,
integral division (aka division without remainder) of two multivariate polynomials
with rational coefficients, Sturm-Habicht sequence and square-free
factorization of a multivariate polynomial with rational coefficients.
The computations are performed by the 'C++' library 'CGAL'
(<https://www.cgal.org/>). Resultants have applications in polynomial
systems solving, number theory, and algebraic geometry. The package
also contains some functions computing the number of real roots of a
univariate polynomial with rational coefficients, and a function computing
the division with remainder of two univariate polynomials with rational
coefficients.
