Formatting a number

To get the number's decimal representation with decimal group separators, and localized digit script, according to the wiki's default locale.

{{formatnum: unformatted number}}

Note: You should use a proper − (−) sign, instead of an - (hyphen).

For example

{{formatnum: -987654321.654321}}

gives

-987,654,321.654321

while

{{formatnum: −987654321.654321}}

gives

−987,654,321.654321

Warning: Leading zeros are not removed (use {{#expr: unformatted number}} to remove them).

For example

{{formatnum: 00001}}

gives

00,001

while

{{formatnum: {{#expr: 00001}} }}

gives

1

Unformatting a number

The |R parameter can be used to unformat (Remove formatting) a number, for use in mathematical situations. The number has to be given with decimal and decimal group separators, and localized digit script, according to the wiki's default locale.

{{formatnum: formatted number|R}}

Note: For a formatted number, you should use a proper − (−) sign, instead of an - (hyphen), although mathematical expressions, e.g. the #expr: parser function, will unfortunately turn it into an hyphen.

For example

{{formatnum: -987,654,321.654321|R}}

gives

-987654321.654321

and

{{#expr: {{formatnum: -987,654,321.654321|R}} }}

gives

-987654321.65432

while

{{formatnum: −987,654,321.654321|R}}

gives

−987654321.654321

and

{{#expr: {{formatnum: −987,654,321.654321|R}} }}

gives

-987654321.65432

Warning: Leading zeros are not removed (use {{#expr: unformatted number}} to remove them).

For example

{{formatnum: 00,001|R}}

gives

00001

while

{{#expr: {{formatnum: 00,001|R}} }}

gives

1
