Template documentation[edit] [history] [purge]

This template tests whether a value is numeric (or at least, that it can be treated as such by the expression ParserFunction).

Usage[edit]

By default, simply writing {{Isnumeric|1,327}} (where 1,327 is an example number) will pass through the parameter if it's numeric and be blank if it's not. If the parameter boolean=true is given, as in {{Isnumeric|1,327|boolean=true}}, then the template will output 1 if numeric and 0 if not numeric.
