Template:Sgn/doc

From Wikipedia, the free encyclopedia

This is a documentation subpage for Template:Sgn (see that page for the template itself).
It contains usage information, categories and other content that is not part of the original template page.

This template evaluates its numeric parameter and returns its mathematical sign. If the parameter is empty or missing, it returns an empty string. Otherwise, the return value is 1 if the parameter is positive, 0 if it is null, -1 if negative.

Syntax:
{{Sgn|value}}
Examples:
  • "{{Sgn|100}}" = "1".
  • "{{Sgn|0.1}}" = "1".
  • "{{Sgn|1-1}}" = "0".
  • "{{Sgn|-0.1}}" = "-1".
  • "{{Sgn|-100}}" = "-1".
