Template:IsNum/Documentation

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

Usage

It has one mandatory string parameter and one optional named parameter:

• 1 is the parameter to be tested; the template will pass through the parameter if it's numeric and return blank if it's not.
• bool (default false — if set to true, the template will output true if numeric and false if not numeric.
