FractionTraits Class Reference

#include <Concepts/FractionTraits.h>

Definition

A model of FractionTraits is associated with a type Type.

In case the associated type is a Fraction, a model of FractionTraits provides the relevant functionality for decomposing and re-composing as well as the numerator and denominator type.

Has Models:

CGAL::Fraction_traits<T>

Member Typedef Documentation

Common_factor

typedef unspecified_type FractionTraits::Common_factor

A model of FractionTraits_::CommonFactor.

Compose

typedef unspecified_type FractionTraits::Compose

A model of FractionTraits_::Compose.

Decompose

typedef unspecified_type FractionTraits::Decompose

A model of FractionTraits_::Decompose.

Denominator_type

typedef unspecified_type FractionTraits::Denominator_type

The (simpler) type to represent the denominator.

This is undefined in case the associated type is not a fraction.

Is_fraction

typedef unspecified_type FractionTraits::Is_fraction

Tag indicating whether the associated type is a fraction and can be decomposed into a numerator and denominator.

This is either CGAL::Tag_true or CGAL::Tag_false.

Numerator_type

typedef unspecified_type FractionTraits::Numerator_type

The type to represent the numerator.

This is undefined in case the associated type is not a fraction.

Type

typedef unspecified_type FractionTraits::Type

The associated type.
