Especially for negative numbers, we have to distinguish between the fractional part of the notation and the fractional part of the number itself, because the latter gets its own decimal sign. The part from the decimal separator to the right is the fractional part if considered as a separate number, a zero is often written in front. The integer part, or integral part of a decimal number is the part to the left of the decimal separator (see also truncation).

) is used as the decimal separator in many other countries, particularly in Europe, a comma is used.

In English-speaking, some Latin American and many Asian countries, a period (. Decimal fractionsĪ decimal fraction is a fraction whose denominator is a power of ten.ĭecimal fractions are commonly expressed without a denominator, the decimal separator being inserted into the numerator (with leading zeros added if needed) at the position from the right corresponding to the power of ten of the denominator e.g., 8/10, 83/100, 83/1000, and 8/10000 are expressed as 0.8, 0.83, 0.083, and 0.0008. However, the symbols used in different areas are not identical for instance, Western Arabic numerals (from which the European numerals are derived) differ from the forms used by other Arab cultures. The symbols for the digits in common use around the globe today are called Arabic numerals by Europeans and Indian numerals by Arabs, the two groups' terms both referring to the culture from which they learned the system. In English, decimal (decimus < Lat.) means tenth, decimate means reduce by a tenth, and denary (denarius < Lat.) means the unit of ten. The English word digit as well as its translation in many languages is also the anatomical term for fingers and toes. Ten is the number which is the count of fingers and thumbs on both hands (or toes on the feet). There were at least two presumably independent sources of positional decimal systems in ancient civilization: the Chinese counting rod system and the Hindu-Arabic numeral system (the latter descended from Brahmi numerals). The position of each digit within a number denotes the multiplier (power of ten) multiplied with that digit-each position has a value ten times that of the position to its right. Positional notation uses positions for each power of ten: units, tens, hundreds, thousands, etc.

These digits are often used with a decimal separator which indicates the start of a fractional part, and with a symbol such as the plus sign + (for positive) or minus sign − (for negative) adjacent to the numeral to indicate whether it is greater or less than zero, respectively. Positional decimal systems include a zero and use symbols (called digits) for the ten values (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) to represent any number, no matter how large or how small. However, when people who use Hindu-Arabic numerals speak of decimal notation, they often mean not just decimal numeration, as above, but also decimal fractions, all conveyed as part of a positional system. Chinese numerals have symbols for 1–9, and additional symbols for powers of 10, which in modern usage reach 10 44. Brahmi numerals have symbols for the nine numbers 1–9, the nine decades 10–90, plus a symbol for 100 and another for 1000.

Roman numerals have symbols for the decimal powers (1, 10, 100, 1000) and secondary symbols for half these values (5, 50, 500). Examples are Roman numerals, Brahmi numerals, and Chinese numerals, as well as the Hindu-Arabic numerals used by speakers of many European languages. 1.4 Non-uniqueness of decimal representationĭecimal notation is the writing of numbers in a base-10 numeral system.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. The contrast here is between decimals and vulgar fractions, and decimal divisions and other divisions of measures, like the inch. There was a notation in use like 'tenth-metre', meaning the tenth decimal of the metre, currently an Angstrom.

In this context, a decimal is a tenth part, and decimals become a series of nested tenths. ĭecimal 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.ĭecimals also refer to decimal fractions, either separately or in contrast to vulgar fractions. It is the numerical base most widely used by modern civilizations. The decimal numeral system (also called base ten or occasionally denary) has ten as its base.
