public class FloatDensity
extends TypedFloatScalarRel<DensityUnit,FloatDensity>

Easy access methods for the Density FloatScalar, which is relative by definition. An example is Speed. Instead of:

 FloatScalar.Rel<DensityUnit> value = new FloatScalar.Rel<DensityUnit>(100.0, DensityUnit.SI);
 

we can now write:

 FloatDensity value = new FloatDensity(100.0, DensityUnit.SI);
 

The compiler will automatically recognize which units belong to which quantity, and whether the quantity type and the unit used are compatible.
