This procedure enable to compute the elements ( is the sum of the roots, the product of the roots). The syntax is:

VECTOR ProdN_Polynomial_Interval(int Degree,VECTOR &Coeff)with:

`Degree`: degree of the polynomial`Coeff`: coefficients of the polynomial ordered along increasing degree

INTERVAL_VECTOR ProdN_Polynomial_Interval(int Degree,INTERVAL_VECTOR &Coeff)which returns intervals including the . This procedure returns 0 if 0 is included in the leading interval.
