round

{{ 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.

The // operator is equivalent to | round(0, 'floor').
