Bản mẫu:Sigfig
0
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.
