Twig Components / Methods / number_format

number_format(decimal = null, decimalPoint = null, thousandSep = null) is a Twig filter to format 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, '.', ',') }}

To format negative numbers or math calculation, wrap the previous statement with parentheses (needed because of Twig's precedence of operators):

{{ -9800.333|number_format(2, '.', ',') }} {# outputs : -9 #}
{{ (-9800.333)|number_format(2, '.', ',') }} {# outputs : -9,800.33 #}
{{  1 + 0.2|number_format(2) }} {# outputs : 1.2 #}
{{ (1 + 0.2)|number_format(2) }} {# outputs : 1.20 #}

If no formatting options are provided then Twig will use the default formatting options of:

• 0 decimal places.
• . as the decimal point.
• , as the thousands separator.

These defaults can be changed through the core extension:

$twig = new \Twig\Environment($loader);
$twig->getExtension(\Twig\Extension\CoreExtension::class)->setNumberFormat(3, '.', ',');

The defaults set for number_format can be over-ridden upon each call using the additional parameters.

Arguments¶

• decimal: The number of decimal points to display
• decimal_point: The character(s) to use for the decimal point
• thousand_sep: The character(s) to use for the thousands separator
