A digit is an element of a set that, taken as a whole, comprises a system of numeration. Thus, a digit is a number in a specific context. In the decimal (base-10) Arabic numbering system, the digits are the elements of the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. The term "digit" is often used to represent a number in a specific position in a larger number, or in a number with a fraction expressed using a radix point. For example, in the decimal number 2609.37, the number 2 is the thousands digit, the number 6 is the hundreds digit, the number 0 is the tens digit, the number 9 is the ones digit, the number 3 is the tenths digit, and the number 7 is the hundredths digit.
