1``round``
2=========
3
4The ``round`` filter rounds a number to a given precision:
5
6.. code-block:: twig
7
8    {{ 42.55|round }}
9    {# outputs 43 #}
10
11    {{ 42.55|round(1, 'floor') }}
12    {# outputs 42.5 #}
13
14The ``round`` filter takes two optional arguments; the first one specifies the
15precision (default is ``0``) and the second the rounding method (default is
16``common``):
17
18* ``common`` rounds either up or down (rounds the value up to precision decimal
19  places away from zero, when it is half way there -- making 1.5 into 2 and
20  -1.5 into -2);
21
22* ``ceil`` always rounds up;
23
24* ``floor`` always rounds down.
25
26.. note::
27
28    The ``//`` operator is equivalent to ``|round(0, 'floor')``.
