What significant figures option means
In everyday life one probably does not need to know that 1 meter is equal to 1.093613 yards. It is probably close enough to say that 1 meter is about 1.09 yards. But in some situations you really need precise values.
That\'s what significant figures switch is for. You can yourself choose how you want you results to be rounded off. The less number of significant figuress you choose, the more your results will be rounded.
The rule is: when you need easy rounded off numbers, switch significant figures to 2 or 3. When you need precision, go for 5 to 7 significant figures.
