The decimal position system, also called the Hindu-Arabic or Arabic system, is a numeral system in which all derived units are based on the number 10 and the powers of 10. The decimal system in nearly universal use today requires ten different symbols, or digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and a decimal point (dot) to represent numbers. In this scheme, the numerals used in denoting a number take different values depending upon position. A number is written as a row of digits, with each position in the row corresponding to a certain power of 10. A decimal point in the row divides the row into those powers of 10 equal to or greater than zero and those less than zero. Positions farther to the left of the decimal point correspond to increasing positive powers of 10 and those farther to the right to increasing negative powers.
