The function root_of computes a real root of a squarefree univariate polynomial.
The function is guaranteed to be well defined in case the value type, NT, of the iterator range is a model of the FieldWithRootOf concept.
#include <CGAL/number_utils.h>
 

 
returns the kth real root of the univariate polynomial,
which is defined by the iterator range,
where begin refers to the constant term.
