Templat:Abs/doc

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}} = |01|.

{{Abs|00}} = |00|.

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

{{Abs|0.0}} = |0.0|.

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

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

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

Examples with an empty (or missing) parameter:

{{Abs|}} = | · |.

{{Abs}} = | · |.
