Template:Abs/doc

From Wikipedia, the free encyclopedia

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. Implemented with the #expr parser function.

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}} =
