Prerequisite

Etymology

QBase is the base class for Quantum.

Synopsis

Quantities are values with a unit. Their basic specification can be one of two forms:

Quantity(Double value, String unit); // or: Unit unit
Quantum<Type> (Type value, String unit) // or: Unit unit

See Quantum for details.

Motivation

To provide the possibilty of mixing units from different Quantum<T1>, Quantum<T2>
