format_number

The format_number filter formats a number:

1

{{ '12.345'|format_number }}

You can pass attributes to tweak the output:

1
2
3
4
5

{# 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:

1
2
3
4
5
6
7
8

{# 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:

1
2
3
4
5

{# 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:

1
2

{# 12.3% #}
{{ '0.12345'|format_percent_number({rounding_mode: 'floor', fraction_digit: 1}) }}

By default, the filter uses the current locale. You can pass it explicitly:

1
2

{# 12,345 #}
{{ '12.345'|format_number(locale='fr') }}
