/**
 * Easy access methods for the ElectricalPotential FloatScalar, which is relative by definition. An example is Speed. Instead
 * of:
 *
 * <pre>
 * FloatScalar.Rel&lt;ElectricalPotentialUnit&gt; value =
 *         new FloatScalar.Rel&lt;ElectricalPotentialUnit&gt;(100.0, ElectricalPotentialUnit.SI);
 * </pre>
 *
 * we can now write:
 *
 * <pre>
 * FloatElectricalPotential value = new FloatElectricalPotential(100.0, ElectricalPotentialUnit.SI);
 * </pre>
 *
 * The compiler will automatically recognize which units belong to which quantity, and whether the quantity type and the unit
 * used are compatible.
