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: Specifies whether to use grouping separator for thousands:

  1

  {{ 123.456789|format_number({significant_digits_used:true, min_significant_digits_used:4, max_significant_digits_used:7}, locale='en') }}

• lenient_parse: If true, allows lenient parsing of the input:

  1
  2

  {# 123 #}
  {{ 123|format_number({lenient_parse:true}, locale='en') }}

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:

  1
  2

  {# 1,234.568 #}
  {{ 1234.56789 | format_number(style='decimal', locale='en') }}

• currency:

  1
  2

  {# $1,234.56 #}
  {{ 1234.56 | format_number(style='currency', locale='en') }}

• percent:

  1
  2

  {# 12% #}
  {{ 0.1234 | format_number(style='percent', locale='en') }}

• scientific:

  1
  2

  {# 1.23456789e+3 #}
  {{ 1234.56789 | format_number(style='scientific', locale='en') }}

• spellout:

  1
  2

  {# one thousand two hundred thirty-four point five six seven eight nine #}
  {{ 1234.56789 | format_number(style='spellout', locale='en') }}

• ordinal:

  1
  2

  {# 1st #}
  {{ 1 | format_number(style='ordinal', locale='en') }}

• duration:

  1
  2

  {# 2:30:00 #}
  {{ 9000 | format_number(style='duration', locale='en') }}

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') }}
