Rounding numbers in Twig

Question

Does someone know how to round down numbers in Twig to the nearest whole number?

Ex : 2.6 => 2

I tried to use |number_format but it doesn't round down them.

Answer 1

@olivierw's answer is correct, but there's another trick you can use. Twig does have // operator which floors down result of division. You can use it as {{ variable // 1 }} which equals to intval(floor(variable)).

Answer 2

Follow the instructions on this page to create your own filter:

$twig = new Twig_Environment($loader);
$twig->addFilter('floor', new Twig_Filter_Function('floor'));

Then in your template:

{{ myNumber|floor }}

Answer 3

Since twig 1.15, you can use round filter.

{{ 2.6|round(0, 'floor') }}
