Introduction
|
|
------------
|
|
|
|
A :code:`basis_unit` represents a unit belonging to a single native dimension.
|
|
For example :code:`bu::meter` representing a distance of 1 meter.
|
|
|
|
.. code-block:: cpp
|
|
|
|
#include <xo/unit/basis_unit.hpp>
|
|
|
|
.. uml::
|
|
:scale: 99%
|
|
:align: center
|
|
:caption: basis unit representing 1 minute
|
|
|
|
object bu1<<basis_unit>>
|
|
bu1 : native_dim = time
|
|
bu1 : scalefactor = 60
|
|
|
|
:code:`basis_unit` is intended as an implementation-level abstraction.
|
|
Application code will normally interact with the more-capable :code:`scaled_unit`
|
|
instead of :code:`basis_unit`.
