#include <CGAL/CORE_Expr.h>

Definition

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.
