  1. Decimal

    The decimal numeral system (also called the base-ten positional numeral system and denary or decanary) is the standard system for denoting integer and non-integer numbers. It is the extension to non-integer numbers of the Hindu–Arabic numeral system. The way of denoting numbers in the decimal system is often referred to as decimal notation.A decimal numeral (also often just decimal or, less correctly, decimal number), refers generally to the notation of a number in the decimal numeral system. Decimals may sometimes be identified by a decimal separator (usually "." or "," as in 25.9703 or 3,1415). Decimal may also refer specifically to the digits after the decimal separator, such as in "3.14 is the approximation of π to two decimals". Zero-digits after a decimal separator serve the purpose of signifying the precision of a value. The numbers that may be represented in the decimal system are the decimal fractions. That is, fractions of the form a/10n, where a is an integer, and n is a non-negative integer. The decimal system has been extended to infinite decimals for representing any real number, by using an infinite sequence of digits after the decimal separator (see decimal representation). In this context, the decimal numerals with a finite number of non-zero digits after the decimal separator are sometimes called terminating decimals. A repeating decimal is an infinite decimal that, after some place, repeats indefinitely the same sequence of digits (e.g., 5.123144144144144... = 5.123144). An infinite decimal represents a rational number, the quotient of two integers, if and only if it is a repeating decimal or has a finite number of non-zero digits.


  1. decimal

    A decimal is a number system based on the number 10, represented in the series of whole numbers followed by a point and a series of numbers indicating a fraction of the whole. The placement of these numbers after the point (known as decimal point) indicates the power of 1/10, for example, in the number 2.34, 3 represents 3/10 and 4 represents 4/100.

Webster Dictionary

  1. Decimaladjective

    of or pertaining to decimals; numbered or proceeding by tens; having a tenfold increase or decrease, each unit being ten times the unit next smaller; as, decimal notation; a decimal coinage

  2. Decimalnoun

    a number expressed in the scale of tens; specifically, and almost exclusively, used as synonymous with a decimal fraction

  3. Etymology: [F. dcimal (cf. LL. decimalis), fr. L. decimus tenth, fr. decem ten. See Ten, and cf. Dime.]


  1. Decimal

    The decimal numeral system has ten as its base. It is the numerical base most widely used by modern civilizations. Decimal notation often refers to a base-10 positional notation such as the Hindu-Arabic numeral system; however, it can also be used more generally to refer to non-positional systems such as Roman or Chinese numerals which are also based on powers of ten. Decimals also refer to decimal fractions, either separately or in contrast to vulgar fractions. In this context, a decimal is a tenth part, and decimals become a series of nested tenths. There was a notation in use like 'tenth-metre', meaning the tenth decimal of the metre, currently an Angstrom. The contrast here is between decimals and vulgar fractions, and decimal divisions and other divisions of measures, like the inch. It is possible to follow a decimal expansion with a vulgar fraction; this is done with the recent divisions of the troy ounce, which has three places of decimals, followed by a trinary place.

Examples of decimal in a Sentence

  1. James Barrett Scotty Reston:

    How Kennedy knew the precise drop in milk consumption in 1960, the percentage rise in textile imports from 1957 to 1960 and the number of speeches cleared by the Defense Department is not quite clear, but anyway, he did.
