Twig Components / Methods / round

Note: You are currently reading the documentation for Bolt 5.0. Looking for the documentation for Bolt 5.2 instead?

round(precision = 0, method = "common") is a Twig filter to round a number to a given precision:

{{ 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
