Quantityinterface. This package provides sub-types for the quantities defined in the International System of Units (SI), together with a few non-SI quantities. Users can create their own quantity types by extending the
This package supports measurable quantities, which can be expressed
Those tuples are not expected to be used directly in numerically intensive code.
They are more useful as metadata converted to the application internal representation

Quantities sub-types are also used as parameterized type to characterize
generic classes and provide additional compile time check. This technic is
used extensively by the
