CGAL 4.5 - Algebraic Foundations
|
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:
and functors :
CGAL::Real_embeddable_traits< RealEmbeddable >::Is_zero
which is a model of RealEmbeddableTraits_::IsZero
CGAL::Real_embeddable_traits< RealEmbeddable >::Abs
which is a model of RealEmbeddableTraits_::Abs
CGAL::Real_embeddable_traits< RealEmbeddable >::Sgn
which is a model of RealEmbeddableTraits_::Sgn
CGAL::Real_embeddable_traits< RealEmbeddable >::Is_positive
which is a model of RealEmbeddableTraits_::IsPositive
CGAL::Real_embeddable_traits< RealEmbeddable >::Is_negative
which is a model of RealEmbeddableTraits_::IsNegative
CGAL::Real_embeddable_traits< RealEmbeddable >::Compare
which is a model of RealEmbeddableTraits_::Compare
CGAL::Real_embeddable_traits< RealEmbeddable >::To_double
which is a model of RealEmbeddableTraits_::ToDouble
CGAL::Real_embeddable_traits< RealEmbeddable >::To_interval
which is a model of RealEmbeddableTraits_::ToInterval
Remark:
If a number type is a model of both IntegralDomainWithoutDivision
and RealEmbeddable
, it follows that the ring represented by such a number type is a sub-ring of the real numbers and hence has characteristic zero.
