Typedefs
typedef Interval_nt< false >	CGAL::Interval_nt_advanced
	This typedef (at namespace CGAL scope) exists for backward compatibility, as well as removing the need to remember the Boolean value for the template parameter.
typedef unspecified_type	CGAL::Exact_integer
	Exact_integer is an exact integer number type.
typedef unspecified_type	CGAL::Exact_rational
	Exact_rational is an exact rational number type, constructible from double.

Typedef Documentation

Exact_integer

typedef unspecified_type CGAL::Exact_integer

#include <CGAL/Exact_integer.h>

Exact_integer is an exact integer number type.

It is a typedef of another number type. Its exact definition depends on the availability the third-party libraries GMP, Core, and LEDA. CGAL must be configured with at least one of those libraries.
