``format_number``
=================
.. versionadded:: 2.12
The ``format_number`` filter was added in Twig 2.12.
The ``format_number`` filter formats a number:
.. code-block:: twig
{{ '12.345'|format_number }}
You can pass attributes to tweak the output:
.. code-block:: twig
{# 12.34 #}
{{ '12.345'|format_number({rounding_mode: 'floor'}) }}
{# 1000000.0000 #}
{{ '1000000'|format_number({fraction_digit: 4}) }}
The list of supported options:
* ``grouping_used``;
* ``decimal_always_shown``;
* ``max_integer_digit``;
* ``min_integer_digit``;
* ``integer_digit``;
* ``max_fraction_digit``;
* ``min_fraction_digit``;
* ``fraction_digit``;
* ``multiplier``;
* ``grouping_size``;
* ``rounding_mode``;
* ``rounding_increment``;
* ``format_width``;
* ``padding_position``;
* ``secondary_grouping_size``;
* ``significant_digits_used``;
* ``min_significant_digits_used``;
* ``max_significant_digits_used``;
* ``lenient_parse``.
Besides plain numbers, the filter can also format numbers in various styles:
.. code-block:: twig
{# 1,234% #}
{{ '12.345'|format_number(style='percent') }}
{# twelve point three four five #}
{{ '12.345'|format_number(style='spellout') }}
{# 12 sec. #}
{{ '12'|format_duration_number }}
The list of supported styles:
* ``decimal``;
* ``currency``;
* ``percent``;
* ``scientific``;
* ``spellout``;
* ``ordinal``;
* ``duration``.
As a shortcut, you can use the ``format_*_number`` filters by replacing `*` with
a style:
.. code-block:: twig
{# 1,234% #}
{{ '12.345'|format_percent_number }}
{# twelve point three four five #}
{{ '12.345'|format_spellout_number }}
You can pass attributes to tweak the output:
.. code-block:: twig
{# €12.34 #}
{{ '12.345'|format_number('EUR', {rounding_mode: 'floor'}) }}
{# €1,000,000.0000 #}
{{ '1000000'|format_number('EUR', {fraction_digit: 4}) }}
By default, the filter uses the current locale. You can pass it explicitly:
.. code-block:: twig
{# 12,345 #}
{{ '12.345'|format_number(locale='fr') }}
.. note::
The ``format_number`` filter is part of the ``IntlExtension`` which is not
installed by default. Install it first:
.. code-block:: bash
$ composer req twig/intl-extra
Then, use the ``twig/extra-bundle`` on Symfony projects or add the extension
explictly on the Twig environment::
use Twig\Extra\Intl\IntlExtension;
$twig = new \Twig\Environment(...);
$twig->addExtension(new IntlExtension());
