FractionTraits_::CommonFactor Concept Reference

Definition

AdaptableBinaryFunction, finds great common factor of denominators.

This can be considered as a relaxed version of AlgebraicStructureTraits_::Gcd, this is needed because it is not guaranteed that FractionTraits::Denominator_type is a model of UniqueFactorizationDomain.

◆ operator()()

result_type FractionTraits_::CommonFactor::operator() ( first_argument_type  d1,
