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:
