CGAL 6.0  Number Types

#include <CGAL/CORE_Expr.h>
The class CORE::Expr
provides exact computation over the subset of real numbers that contains integers, and which is closed by the operations \( +,,\times,/,\sqrt{}\) and \(\sqrt[k]{}\).
Operations and comparisons between objects of this type are guaranteed to be exact. This number type is provided by the Core library [3].
CGAL defines the necessary functions so that this class complies to the requirements on number types.
