Template:Isnumeric/doc

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

Usage
By default, simply writing 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  is given, as in 1,327, then the template will output   if numeric and   if not numeric.
