Category:Pages with non-numeric formatnum arguments

Administrators: Please do not delete this category even if it is empty.

This is a maintenance category. It is used for maintenance of the Wikimedia project and is not part of the encyclopedia. It contains pages that are not articles, or it groups articles by status rather than subject. Do not include this category in content categories. This is a hidden category. It is not shown on its member pages, unless the corresponding user preference 'Show hidden categories' is set. This is a tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. Pages are added to tracking categories through templates. This category collects pages that use the formatnum parser function with non-numeric parameters, e.g. {{formatnum:foo}}.

This category collects pages that use the formatnum parser function with a non-numeric or incorrectly formatted value, e.g. {{formatnum:foo}} or {{formatnum:12,345}}.

Ways to fix or work around this error inside template code:

• If formatnum is being applied to a string that includes both a number and words, change it to wrap just the number. Example: {{formatnum:{{{var}}} dollars}} → {{formatnum:{{{var}}}}} dollars
• Another way to work around invalid input is to remove commas from the input like this: {{formatnum:{{replace|{{{var}}}|,|}}}}. Note that input using commas as decimal separators, in contravention of MOS:DECIMAL, will cause formatnum to produce invalid values. To fix the problem, use a full stop (period) as a decimal separator.
• A limited way to work around invalid input in templates is to use {{digits}}, e.g. {{formatnum:{{digits|{{{votes}}}}}}}. This works only for whole numbers and will produce incorrect results for input containing decimal points or other non-numeric characters.

Ways to fix this error in articles:

• When additional text or references exists in a template parameter that expects only numbers, find a way to move the additional text outside the template or into a different parameter. For example:
  • Currency templates like {{CAD}} or {{US$}} take only numeric input. Use {{US$|123}}{{nbsp}}million instead of {{US$|123 million}}
  • The |population_total= parameter in {{Infobox settlement}} should have only a number in it. Move any references to |population_footnotes=, as in this edit.

False positives:

• When formatnum is given a negative number written with the proper U+2212 "minus sign" (instead of the commonly used en:hyphen-minus hyphen-minus key that appears on most keyboards), e.g. {{formatnum:−9000000}}, it assigns this error category; see task T237467. A workaround for this incorrect usage was applied to {{US Census population}}, which shows population declines as negative numbers. Another workaround, if having this error category on a page bothers you, is to use a en:hyphen-minus hyphen-minus within formatnum to avoid this error category; note that it does not output a proper minus sign; see task T10327.
