Package orbital.math.functional Description

Contains mathematical functors and extended functional operations.

This package is dual to orbital.logic.functor, it provides mathematical extensions that inherit from logic functors (that are in turn derived from orbital.logic.functor.Functor) in a conform way. Mathematical functors extend their logic counterpart and additionally implement orbital.math.functional.MathFunctor.
So for instance there's an interface orbital.math.functional.BinaryFunction that extends both, orbital.logic.functor.BinaryFunction and orbital.math.functional.MathFunctor.
Though this might see a little subtile it has the advantage that methods written for general logical functors will work for mathematical functors as well. So both types of functors are rather compatible.

The class orbital.math.functional.Functionals defines High-Order-Functions for functional style evaluation. With Functionals one can apply Functions to collections and arrays of values as well as compose functions. Mathematical operations for major mathematical functions are pre-defined in the class orbital.math.functional.Operations. Usual mathematical functions are provided in orbital.math.functional.Functions
