Category:Pages with non-numeric formatnum arguments

From Wikipedia, the free encyclopedia

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 exist 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.


  • When formatnum is given a negative number written with the proper U+2212 "minus sign" (instead of the commonly used hyphen-minus key that appears on most keyboards), e.g. {{formatnum:−9000000}}, it assigns this error category; see T237467. A workaround for this incorrect usage was applied to {{US Census population}}, which shows population declines as negative numbers. You should use hyphen-minus within formatnum to avoid this error category and it will output the proper minus sign (see T10327).
