		If the decimal is moved to the left, then the exponent will be positive – the number of times the decimal is moved.
		If the decimal is moved to the right, then the exponent will be negative – the number of times the decimal is moved.
		If the "coefficient number" becomes larger after moving the decimal, decrease the exponent by the number of times the decimal is moved.

	Decimal - Wikipedia, the free encyclopedia
		A decimal fraction is a fraction where the denominator is a power of ten.
		Decimal 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.
		A straightforward decimal system, in which 11 is expressed as ten-one and 23 as two-ten-three, is found in Chinese languages except Wu, and in Vietnamese with a few irregularities.

		Decimal notation is the writing of numbers in the base-ten numeral system, which uses various symbols (called digits) for ten distinct values (0, 1, 2, 3, 4, 5, 6, 7, 8 and 9) to represent numbers.
		Decimal arithmetic is used in computers so that fractional results can be computed exactly, which is not possible using a binary fractional representation.
		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.

	Decimals, Whole Numbers, and Exponents
		Decimal numbers such as 3.762 are used in situations which call for more precision than whole numbers provide.
		The expanded form of a decimal number is the number written as the sum of its whole number and decimal place values.
		To round a number to any decimal place value, we want to find the number with zeros in all of the lower places that is closest in value to the original number.

		If the power of ten is positive, the decimal form of the number (the "normal" system of writing the number) would have the decimal part with the decimal moved the indicated number of spaces to the right.
		To change a number from decimal notation to scientific notation, insert a decimal place so that there is one nonzero digit to the left of it.
		The arithmetic is done on the decimal parts and the rules for exponents are used to determine the power of ten.

		In this notation any number is expressed as a number between 1 and 10 multiplied by the appropriate power of 10.
		To convert a number to scientific notation, the decimal point must first be located.
		An interesting fact to note is that multiplying a decimal number by a power of ten is equivalent to moving the decimal point a certain number of spaces to the right (where that number is equal to the power of ten in the multiplier).

	Decimal Squares Philosophy and Purpose
		The main purposes of the Decimal Squares program are to provide students with conceptual understanding of decimal notation and operations and to help them become competent in using decimals and performing operations.
		Unlike the lengthy readiness period for whole numbers and their operations, decimal notation and their operations are often taught with little attention to models for understanding decimal concepts.
		While the base ten blocks can be used to illustrate the important concept that the decimal for a quantity depends on the unit, it appears that this model may cause confusion for some students when it is first used to model whole numbers and later used to model decimals.

	ANSDIT - The letter "B"
		A binary-coded notation in which each of the decimal digits is separately represented by a binary numeral.
		For example, in the binary-coded decimal notation that uses the weights 8-4-2-1, the decimal numeral 23 is represented by 0010 0011 as compared to its representation 10111 in the binary system.
		A notation in which each number n from 0 to 9 is represented by the pair of numerals a,b, where a is 0 or 1, b is 0, 1, 2, 3, or 4 so that the sum of 5a+b is equal to n.

	Scientific Notation
		You should move the decimal point until there is exactly one nonzero digit to the left of the decimal point, as in the last case of each example given.
		If you are given a number in scientific notation to raise to a power, remember that all this means is that it is used as a factor that many times.
		Do this by moving the decimal point of the coefficient of that number to the left, and adding one to the exponent of that number, until the two exponents are equal.

		This place holding or place notation was much easier than inventing a new character for each number (imagine having to memorize an enormous number of characters just to read the date!).
		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.
		The first evidence of decimals in Europe is in a Spanish manuscript of 976 AD by Gerbert, who had studied under Arabic mathematicians.

	The Decimal System
		In the decimal system, ten different digits are used to represent numbers with a base of ten.
		This process is not necessarily exact; that is, a decimal fraction with a finite number of digits may require a binary fraction with an infinite number of digits.
		It is used as a concise notation for representing any sequence of binary digits, whether they represent text, numbers, or some other type of data.

	Stevin's Decimal Magic
		Stevin is often referred to as the inventor of the decimal fraction and thus he was important because he brought to common usage our method of adding, subtracting, multiplying, and dividing numbers that contain decimals.
		Stevin may have borrowed from a decimal value notation of Bombelli, who used a half circle with a number to denote a geometric regression of ten from each place value to the right of an integer.
		The Chinese apparently were using decimal place-value notation as early as 1400 B.C. The decimal system was a natural one with man’s anatomically suited digits.

	Chemistry 103 Writing Numbers in Exponential Notation
		An easier method of converting a number to exponential notation is to note the direction and number of places you had to move the decimal point to leave just one digit to the left of the decimal point.
		If the decimal moves to the left, the exponent on 10 is equal to the number of places the decimal was moved and has a positive sign.
		If the decimal moves to the right, the exponent on 10 is equal to the number of places the decimal was moved and has a negative sign.

		Since decimal notation is built on the idea of powers of 10, and percent notation is based on division by 100, these two notations are very compatible and easy to switch between.
		Identify the decimal in the number in front of the percent sign.
		The reason for moving the decimal 2 places to the left is that you are dividing the number by 100; this operation makes the number smaller, and it does so by 2 decimal places.

	SparkNotes: Measurements: Scientific Notation
		Until now, we have been writing numbers in "decimal notation." Sometimes, especially with large numbers, we need to convert numbers into scientific notation.
		Observe: the exponent on "10" corresponds to the number of places that the decimal point has moved--it is positive if the decimal point has moved to the left and negative if it has moved to the right.
		One of the trickiest things about scientific notation is remembering the rules for zeros: if a number ends in one or more zeros, do not include the zeros if the number is a whole number, but do include the zeros if the number is a decimal.

	What are binary, octal, and hexadecimal notation? - Knowledge Base
		In normal decimal (base-10) notation, each digit, moving from right to left, represents an increasing order of magnitude (or power of ten).
		With decimal notation, each succeeding digit's contribution is ten times greater than the previous digit.
		The concept is the same with binary notation, except that each digit is a power of two greater than the preceding digit, rather than a power of ten.
