| ``round`` |
| ========= |
| |
| The ``round`` filter rounds a number to a given precision: |
| |
| .. code-block:: twig |
| |
| {{ 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')``. |
