RealEmbeddable

Definition

A model of this concepts represents numbers that are embeddable on the real axis. The type obeys the algebraic structure and compares two values according to the total order of the real numbers.

Moreover, CGAL::Real_embeddable_traits< RealEmbeddable > is a model of RealEmbeddableTraits
with:
- CGAL::Real_embeddable_traits< RealEmbeddable >::Is_real_embeddable set to Tag_true
and functors :
- CGAL::Real_embeddable_traits< RealEmbeddable >::Is_zero
- CGAL::Real_embeddable_traits< RealEmbeddable >::Abs
- CGAL::Real_embeddable_traits< RealEmbeddable >::Sgn
- CGAL::Real_embeddable_traits< RealEmbeddable >::Is_positive
- CGAL::Real_embeddable_traits< RealEmbeddable >::Is_negative
- CGAL::Real_embeddable_traits< RealEmbeddable >::Compare
- CGAL::Real_embeddable_traits< RealEmbeddable >::To_double
- CGAL::Real_embeddable_traits< RealEmbeddable >::To_interval

Remark:
If a number type is a model of both IntegralDomainWithoutDivision and RealComparable, it follows that the ring represented by such a number type is a sub-ring of the real numbers and hence has characteristic zero.
