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. More...
 
typedef unspecified_type CGAL::Exact_rational
 Exact_rational is an exact rational number type, constructible from double. More...
 

Typedef Documentation

◆ 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.

Is Model Of:

EuclideanRing

RealEmbeddable

◆ Exact_rational

#include <CGAL/Exact_rational.h>

Exact_rational is an exact rational number type, constructible from double.

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.
