Template:Abs

Template documentation[view] [edit] [history] [purge]

This template evaluates its numeric parameter and returns its absolute value. If the parameter is empty or missing, it returns an empty string. The parameter may also be a numeric expression that will be evaluated before testing its sign.

Syntax:

{{Abs|value}}

Examples with a simple number:

{{Abs|100}} = 100.

{{Abs|0.1}} = 0.1.

{{Abs|0}} = 0.

{{Abs|-0.1}} = 0.1.

{{Abs|-100}} = 100.

Examples where the parameter is evaluated:

{{Abs|01}} = 1.

{{Abs|00}} = 0.

{{Abs|0.}} = 0.

{{Abs|0.0}} = 0.

{{Abs|-0}} = -0.

{{Abs|3-4}} = 1.

{{Abs|-4*2}} = 8.

Examples with an empty (or missing) parameter:

{{Abs|}} = .

{{Abs}} = .
