TheĀ decimalĀ numeral systemĀ (also calledĀ base-tenĀ positional numeral system, and occasionally calledĀ denary) is the standard system for denotingĀ integerĀ and non-integerĀ numbers. It is the extension to non-integer numbers of theĀ HinduāArabic numeral system.[1]Ā The way of denoting numbers in the decimal system is often referred to asĀ Decimal notation.[2]
AĀ decimal numeral, or justĀ decimal, or, improperlyĀ decimal number, refers generally to the notation of a number in the decimal system, which contains aĀ decimal separator(for example 10.00 or 3.14159). Sometimes these terms are used for any numeral in the decimal system. AĀ decimalĀ may also refer to any digit after the decimal separator, such as in "3.14 is the approximation ofĀ ĻĀ to two decimals".
The numbers that may be represented in the decimal system are theĀ decimal fractions, that is theĀ fractionsĀ of the formĀ a/10n, whereĀ aĀ is an integer, andĀ nĀ is aĀ nonnegative integer.
