Template:IsNumber/doc

This template is used to determine whether an input is a number. This is useful in cases where it is ambiguous if, for instance, the value of a template parameter is the name or the ID of an item.

It only recognizes purely numerical strings, i.e., strings consisting of one or more digits. Spaces within (but not around) the number, or thousands or decimal separators are not considered.

Usage
The string which is to be checked if it consists of a number.
 * First unnamed parameter
