In this section, we learn how to round whole numbers. Rounding a whole number is a way to give an estimate or value that is close,
but not exactly the same as the original. To round a whole number, first we identify the digit in the round off place. Second we look at the digit one place to the right. If this
digit is 4 or less we keep the digit in the round off place as is and change every digit that follows into a zero. If this digit is 5 or greater, we add one to the digit in the round
off place, and change every digit that follows into a zero.
