New in version 1.5: The number_format filter was added in Twig 1.5
The number_format filter formats numbers. It is a wrapper around PHP’s number_format function:
{{ 200.35|number_format }}
You can control the number of decimal places, decimal point, and thousands separator using the additional arguments:
{{ 9800.333|number_format(2, '.', ',') }}
If no formatting options are provided then Twig will use the default formatting options of:
These defaults can be easily changed through the core extension:
$twig = new Twig_Environment($loader);
$twig->getExtension('core')->setNumberFormat(3, '.', ',');
The defaults set for number_format can be over-ridden upon each call using the additional parameters.
