Twig: How to round up?

Update

On versions 1.15.0+, round filter is available.

{{ (7 / 2)|round(1, 'ceil') }}

You can extend twig and write your custom functions as it is described here

And it will be something like this:

<?php
// src/Acme/DemoBundle/Twig/AcmeExtension.php
namespace Acme\DemoBundle\Twig;

class AcmeExtension extends \Twig_Extension
{
    public function getFilters()
    {
        return array(
            'ceil' => new \Twig_Filter_Method($this, 'ceil'),
        );
    }

    public function ceil($number)
    {
        return ceil($number);
    }

    public function getName()
    {
        return 'acme_extension';
    }
}

So you can you use it in twig:

(7 / 2) | ceil

New in version 1.15.0: The round filter was added in Twig 1.15.0.

Example: {{ 42.55|round(1, 'ceil') }}

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)

No idea how it is in previous versions, but in Symfony 2.2.1 you have to use parenthesis around your calculation (assuming you created the extension):

(7 / 2)|ceil

Apparently 7 / 2|ceil is the same as 7 / (2|ceil) since they both gave the same (wrong) result and only the above solution worked for me.

Have you tried 7 // 2?
