Template:Significant figures/doc
Appearance
This is a documentation subpage for Template:Significant figures. It may contain usage information, categories and other content that is not part of the original template page. |
This template is used on approximately 5,300 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them. |
This template has two different functions dependent on input.
- If only one parameter is given the template counts the number of significant figures of the given number within the ranges 1012 to 10−12 and −10−12 to −1012. It ignores any digits outside this range.
- If two parameters are given the template rounds the first number to the number of significant figures given by the second.
