		It is believed that the decimal system is based on 10 because humans have 10 fingers and so became used to counting by 10s early in the course of civilization.
		A number written in the decimal system is called a decimal, although sometimes this term is used to refer only to a proper fraction written in this system and not to a mixed number.
		Decimals are added and subtracted in the same way as are integers (whole numbers) except that when these operations are written in columnar form the decimal points in the column entries and in the answer must all be placed one under another.

	Decimal - Wikipedia, the free encyclopedia
		Decimal notation is the writing of numbers in the base-ten numeral system, which uses various symbols for ten distinct quantities (0, 1, 2, 3, 4, 5, 6, 7, 8 and 9, called digits) to represent numbers.
		Decimal fractions can be expressed without a denominator, the decimal point 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.
		That a rational must produce a finite or recurring decimal expansion can be seen to be a consequence of the long division algorithm, in that there are only (q-1) possible nonzero remainders on division by q, so that the recurring pattern will have a period less than q-1.

	Metric System - MSN Encarta
		All units of measurement in the metric system are based on decimals—that is, units that increase or decrease by multiples of ten.
		A series of Greek decimal prefixes is used to express units of ten or greater; a similar series of Latin decimal prefixes is used to express fractions.
		To change units in the metric system, simply move the decimal point to the right or the left, depending on whether the unit of measurement is increasing or decreasing by ten or one hundred and so on.

	Dewey Decimal Classification - Wikipedia, the free encyclopedia
		The Dewey Decimal Classification (DDC, also called the Dewey Decimal System) is a system of library classification developed by Melvil Dewey in 1876, and since greatly modified and expanded in the course of the twenty-two major revisions, the most recent in 2004.
		DDC's cleverness is in choosing decimals for its categories; this allows it to be both purely numerical and infinitely hierarchical.
		Despite its frequent revision, DDC is widely considered theoretically inferior to other more modern systems which make freer use of alphabetical characters to produce shorter classmarks for concepts of equal complexity, though it continues to offer a more expressive format than the Library of Congress Classification developed shortly afterward..

		The modern system of decimal numbers was introduced, along with so-called Arabic numerals, to Europe in the thirteenth century, although the Arabs learned them from the Indians (who may have learned it from the Chinese) centuries earlier.
		Decimal numbers may also be used to represent fractions, by the use of decimal fractions.
		Decimal fractions continue to the right of the right-most digit, seperated from the whole part of the number by a "decimal sign." In English-speaking countries, the decimal sign is a dot or point, called the "decimal point".

	Yosemite Decimal System -- Facts, Info, and Encyclopedia article (Site not responding. Last check: 2007-11-05)
		Previously, hikes and climbs were described relative to others ("harder than X, but easier than Y"), but this made it difficult for those who hadn't done the other hikes or climbs to understand the comparison, so the numerical grading system was an attempt to codify this into a single scale.
		The increasing technical difficulty of Class 5 climbs led to the same "relative grading" problem that had caused the initial development of the system, so that class was subdivided in the 1950s.
		Initially it was based on ten climbs in Taquitz, California, and ran from "The Trough" at 5.0, a relatively modest technical climb, to "The Open Book" at 5.9, considered at the time the most difficult unaided climb humanly possible.

	Dewey Decimal Classification - LISWiki
		The Dewey Decimal Classification (DDC, also called the Dewey Decimal System) is a proprietary system of library classification developed by Melvil Dewey in 1876, and has since then been greatly modified and expanded through twenty-two major revisions, the most recent in 2004.
		On the flip side, DDC's decimal system means that it is less hospitable to the addition of new subjects, as opposed to Library of Congress Classification which has 21 classes at the top level.
		As a result, while the Library of Congress Classification system was able to incorporate changes and additions of new branches of knowledge, particularly in the fields of engineering and computer science (the greater hospitability of the Library of Congress Classification was also a factor), DDC has been criticized for being inadequate for covering those areas.

	Decimal Time - Metric Time
		Slightly different versions of the metric system were developed by different specialists in different countries, which were all replaced in 1960 by the modernized metric system, the International System of Units (SI).
		For a decimal reform, a decimal fraction of the day must be selected for the new base unit, such as 1 d, 0.1 d, 0.01 d, etc. A whole day is the most obvious choice, since it is the the most important natural time period, and is already a frequently used unit.
		The "decimal second" (0.00001 or 1/100,000 day) has been proposed as the new base unit, because it is close to the SI second, and would be more convenient for deriving secondary units, although there is inconveniently no metric multiple equal to a whole day.

		Mathematics commonly uses a positional numeral system employing 10 as the base and requiring 10 different numerals, the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and a dot (decimal point).
		Most historians agree that the development of a decimal place value system of numeration originated from the Indian subcontinent, and that Arabic scholars were responsible for the system.
		While it cannot be denied that the Babylonians used a place value system, theirs was sexagismal (base 60), and while the concept of place value may have come from Mesopotamia, the Indians were the first to use it with a decimal base (base 10).

		In 1670, Gabriel Mouton, a theologian and mathematician from Lyon, France proposed the general use of the decimal system and suggested a standard linear measurement based on the length of the arc of one minute of longitude on the Earth's surface and divided decimally (by ten).
		The system was made legal (but not mandatory) in the US by the Metric Act of 1866, and the US also was a signatory of the Treaty of the Metre in 1875.

	Babylonian numerals
		Yet neither the Sumerian nor the Akkadian system was a positional system and this advance by the Babylonians was undoubtedly their greatest achievement in terms of developing the number system.
		Although not a very serious comment, perhaps it is worth remarking that if we assume that all our decimal digits are equally likely in a number then there is a one in ten chance of an empty place while for the Babylonians with their sexagesimal system there was a one in sixty chance.
		However although Neugebauer may be correct, the counter argument would be that the system of weights and measures was a consequence of the number system rather than visa versa.

	Decimal Arithmetic - FAQ 3
		However, for all of these machines, only integer decimal arithmetic is supported, and for most the support is limited to decimal adjustment or conversion instructions which simplify decimal operations.
		Decimal arithmetic, therefore, is inherently less efficient than binary arithmetic, and at the time this justified the switch to binary floating-point arithmetic (just as a two-digit representation for the year in a date was justifiable at the time).
		In contrast, a native hardware decimal type could reduce this to a speed comparable to binary arithmetic (which is 41 cycles for integer division on the Pentium, or 3 for an addition).
