	What is octal? - A Word Definition From the Webopedia Computer Dictionary
		Programs often display data in octal format because it is relatively easy for humans to read and can easily be translated into binary format, which is the most important format for computers.
		By contrast, decimal format is the easiest format for humans to read because it is the one we use in everyday life, but translating between decimal and binary formats is relatively difficult.
		For example, the octal number 3456 is 011 100 101 110 in binary.

	Octal Number System
		The typical method to convert from decimal to octal is repeated division by 8.
		This process is continued by dividing he quotient by 8 and writing the remainder until the quotient is 0.
		When performing the division, the remainders which will represent the octal equivalent of the decimal number are written beginning at the least significant digit (right) and each new digit is written to the next more significant digit (the left) of the previous digit.

	Octal Audio Buffer
		The Murraypro OCTAL BUFFER is an extremely flexible audio buffer designed for general interface use in the Broadcast Industry.
		These are the preferred connector type since the full flexibility of the Octal Buffer is always maintained, whilst enabling the use of cost effective IDC wiring technology within the Frame.
		We always recommend that unbalanced inputs are wired as if they were balanced, ie with screened twin cable from the source, thus permitting the common mode rejection ratio of the balanced input amplifiers to be used to full advantage, for hum reduction on the input line.

	Octal Summary
		Octal numerals can be made from binary numerals by grouping consecutive digits into groups of three (starting from the right).
		Octal is sometimes used in computing instead of hexadecimal, perhaps most often in modern times in conjunction with file permissions under Unix systems (see chmod).
		Octal is converted to binary and then to hexadecimal, grouping digits 4 by 4, which correspond each to an hexadecimal digit.

		Octal counting may have been used in the past instead of decimal counting, by counting either the gaps between fingers or the non-thumb fingers.
		Octal is as good as binary and hexadecimal for fractions, since the only prime factors for their bases are 2.

	Octal Number System
		The techniques used to convert decimal fractions to octal are similar to the methods demonstrated previously to convert decimal fractions to binary numbers.
		The primary application of octal numbers is representing binary numbers, as it is easier to read large numbers in octal form that in binary form.
		Because each octal digit can be represented by a three-bit binary number (see Table 2-5), it is very easy to convert from octal to binary.

	Octal and hexadecimal numeration - Chapter 1: NUMERATION SYSTEMS - Volume IV - Digital (Site not responding. Last check: )
		Octal and hexadecimal numeration systems would be pointless if not for their ability to be easily converted to and from binary notation.
		Because the bases of octal (eight) and hexadecimal (sixteen) are even multiples of binary's base (two), binary bits can be grouped together and directly converted to or from their respective octal or hexadecimal digits.
		Likewise, the conversion from either octal or hexadecimal to binary is done by taking each octal or hexadecimal digit and converting it to its equivalent binary (3 or 4 bit) group, then putting all the binary bit groups together.

	Computer Science - Octal and Hexidecimal
		Octal and hexidecimal numbers are number systems that use a different number of bases.
		Octal is simply a number system that is base-8, and hexidecimal is a number system that is base-16.
		Therefore, the octal number 144 is equivalent to the decimal number of 100.

	Octal and Hexadecimal Character Specifications (C/C++ Language Reference)
		Octal escape sequences can never be longer than three digits and are terminated by the first character that is not an octal digit.
		For example, the octal representation is \10 for the ASCII backspace character and \101 for the letter A, as given in an ASCII chart.
		The value of the octal or hexadecimal escape sequence must be in the range of representable values for type unsigned char for a character constant and type wchar_t for a wide-character constant.

	Octal and hexadecimal to decimal conversion - Chapter 1: NUMERATION SYSTEMS - Volume IV - Digital (Site not responding. Last check: )
		Although the prime intent of octal and hexadecimal numeration systems is for the "shorthand" representation of binary numbers in digital electronics, we sometimes have the need to convert from either of those systems to decimal form.
		Of course, we could simply convert the hexadecimal or octal format to binary, then convert from binary to decimal, since we already know how to do both, but we can also convert directly.
		Because octal is a base-eight numeration system, each place-weight value differs from either adjacent place by a factor of eight.

	OCTAL - Definition
		Octal system used to be widespread back when many computers used 6-bit bytes, as a 6-bit byte can be conveniently written as a two-digit octal number.
		Since nowadays a byte is almost always 8-bit long the octal system lost most of its appeal to the hexadecimal system.

	Computer Arithmetic - The Octal Number System
		Since the octal number 10 follows 7, 10 in octal is 8 in decimal.
		That is, 3034 in decimal is 5732 in octal.
		We can simplify this procedure by noticing that the first remainder will be the last digit in the octal number; the second remainder will be the second digit from the right; and so on.

		The correspondence between octal and binary numerals is the same as for the first eight digits of hexadecimal in the table above.
		Binary 000 is equivalent to the octal digit 0, binary 111 is equivalent to octal 7, and so on.
		Non-integers can be represented by using negative powers, which are set off from the other digits by means of a radix point (called a decimal point in the decimal system).

	* Octal - (Computing): Definition
		Octal (pronounced AHK-tuhl, from Latin octo or "eight") is a term that describes a base-8 number system.
		The base-8 number system consisting of the digits 0 through 7, from the Latin octo, meaning "eight." The octal system is used in programming as a compact means of representing binary numbers.
		It is used as a shorthand method for representing binary characters that use six-bits.

	What are binary, octal, and hexadecimal notations?
		Octal notation represents data as a base-8 number.
		Octal numbers use only the digits 0-7, while hexadecimal numbers use all ten base-10 digits (0-9) and the letters a-f (represent the numbers 10-15).
		It can sometimes be difficult to tell whether data is being represented as octal, or hexadecimal (especially if a hexadecimal number doesn't use one of the digits 8-f), so one convention that is often used to distinguish these is to put
