Template:Significant figures

This template has two different functions dependant on input.

1. 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 of this range.
2. If two parameters are given the template rounds the first number to the number of significant figures given by the second.
