Full Answer

The decimal system has 10 as its base, and is sometimes known as a base-10 system. The system incorporates whole numbers and decimal fractions. Whole numbers appear before the period, and fractions appear as decimal digits after it. The position of every decimal digit is determined by the power to which the denominator, 10, is raised.
