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.

the associated type
| |
|
| |
|
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.
| |
|
| |
|
The type to represent the numerator.
This is undefined in case the associated type is not a fraction.
| |
|
| |
|
The (simpler) type to represent the denominator.
This is undefined in case the associated type is not a fraction.
| |
In case Type is not a Fraction all functors are Null_functor.
