CORE::Expr

Definition

The class CORE::Expr provides exact computation over the subset of real numbers that contains integers, and which is closed by the operations +,-, × ,/,√ and kth_root. Operations and comparisons between objects of this type are guaranteed to be exact. This number type is provided by the Core library [KLPY99].

Cgal defines the necessary functions so that this class complies to the requirements on number types.
