All Superinterfaces:

Arithmetic, Normed

All Known Subinterfaces:

Complex, Integer, Rational, Real

public interface Scalar
extends Arithmetic

Abstraction of all scalar arithmetic number objects.

This class is the base class for all Arithmetic objects of scalar number type. Scalars usually implement Comparable as well. Most scalar implementation also tend to extend Number but are not required to do so, since that would break the freedom of inheriting from another base class.
