Additional functions provide the support for operations that result in a
different dimension type than those of their arguments. ``equivalent_dim``
different dimension type than those of their arguments. ``equivalent``
constraint requires two dimensions to be either the same or have convertible
units of base dimension (with the same reference unit).
