The class *CORE::Expr* provides exact computation over the subset of real
numbers that contains integers, and which is closed by the operations
$$*+,-, × ,/* and $$*sqrt()*. Comparisons between objets 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.
