CGAL 4.12  Modular Arithmetic

An algebraic structure is called Modularizable
, if there is a suitable mapping into an algebraic structure which is based on the type CGAL::Residue
. For scalar types, e.g. Integers, this mapping is just the canonical homomorphism into the type CGAL::Residue
with respect to the current prime. For compound types, e.g. Polynomials, the mapping is applied to the coefficients of the compound type.
The mapping is provided via CGAL::Modular_traits<Modularizable>
, being a model of ModularTraits
.
Note that types representing rationals, or types which do have some notion of denominator, are not Modularizable
. This is due to the fact that the denominator may be zero modulo the prime, which can not be represented.
