Introduction
|
|
------------
|
|
|
|
Constants in the :code:`xo::qty::detail::bu` namespace represent
|
|
low-level building blocks for specifying units.
|
|
Relative scalefactors for each unit are chosen here.
|
|
|
|
Application code will not typically use these values directtly;
|
|
instead it's expected to use units from the :code:`xo::qty::u` namespace.
|
|
Those units are implemented on top of the basis units described here.
|
|
|
|
.. code-block:: cpp
|
|
|
|
#include <xo/unit/basis_unit.hpp>
|
|
|
|
using xo::qty::detail::bu;
