The {{abs}} mathematical function template returns the absolute value of a real number, otherwise returns an error message.

Usage

{{abs|a real number}}

You may also use the abs operator in a mathematical expression for a numerical argument of a template, e.g.

{{expr|abs a_real_number}}

or in a mathematical expression for a numerical argument of a parser function, e.g.

{{#expr: abs a_real_number }}

Valid input

An unformatted real number. (Cf. Formatted numbers)

Examples
