``round``
=========
.. versionadded:: 1.15.0
The ``round`` filter was added in Twig 1.15.0.
The ``round`` filter rounds a number to a given precision:
.. code-block:: jinja
{{ 42.55|round }}
{# outputs 43 #}
{{ 42.55|round(1, 'floor') }}
{# outputs 42.5 #}
The ``round`` filter takes two optional arguments; the first one specifies the
precision (default is ``0``) and the second the rounding method (default is
``common``):
* ``common`` rounds either up or down (rounds the value up to precision decimal
places away from zero, when it is half way there -- making 1.5 into 2 and
-1.5 into -2);
* ``ceil`` always rounds up;
* ``floor`` always rounds down.
.. note::
The ``//`` operator is equivalent to ``|round(0, 'floor')``.
Arguments
---------
* ``precision``: The rounding precision
* ``method``: The rounding method
