<h3>What is significant figures?</h3>
Significant figures are those figures that are meaningful with respect to the precision of a measurement.
In other words, a digit that is nonzero, followed by a nonzero digit,or (for trailing zeroes) justified by the precision of the derivation or measurement is a significant figure.
