`quantity_cast` in line #1 takes a specific target `quantity` type to which an explicit
cast should be performed. This option will change multiple quantity properties at once
(unit, representation, etc). However, it is also possible to force only one property at
(unit, representation, etc). However, it is also possible to force only some properties at
once and leave the rest intact:
- line #2 forces only a specific destination unit type,
- line #3 sets only a representation type to the type provided by the user.
- line #2 forces only a specific destination dimension type,
- line #3 forces only a specific destination unit type,
- line #4 sets only a representation type to the type provided by the user,
- line #5 forces both a specific dimension and a unit while preserving the original
representation type.
`quantity_point_cast` takes anything that works for `quantity_point`
or a specific target `quantity_point`::
