Definitions for **"Hexadecimal"**

Counting system based on 16.

Although Binary numeration is the base of computer numbering, it is cumbersome to deal with 1s and 0s. It turns out, however, that the system can be subsumed into a more convenient numbering system which allows a more accessible numbering convention. To do this, a system based on the number 16 is used. Sixteen is 2 x 4. A four digit binary number ( e.g. 0110, 0010, 1000 ) can be represented by a single hexadecimal number. the Hexadecimal digits are 0 to F. This is actually 0 to 9 and A to F. So A represents 10 ( in normal decimal notation), B represents 11 and so on. So the binary number 1001 0011 1110 can be represented in HEX (short for Hexadecimal) as 93E. Much more convenient.

the base sixteen number system. The digits used are 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E, & F. You will see some values expressed in hex on some Digitrax throttles because with this system you can express numbers above decimal 99 as two digits.

The base 16 number system. Digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, & F. This is a convenient form in which to examine binary data because it collects 4 binary digits per hexadecimal digit; e.g., decimal 15 is 1111 in binary and F in hexadecimal.

A base-16 number system where each digit may contain a value 0-9 or A-F. For example, the decimal number 255 can represented in two digits with the hexadecimal equivalent being FF. Used in computer programming and HTML code.

Base 16. A number notation that uses 16 possible values, 0-9 and A-F. The most common notation used in the computer world.

A system of whole numbers with a base of 16 used in certain computer operations. Hexadecimal coding uses numerals 0 to 16 with the first 10 digits represented by 0 through 9 and the next 6 digits represented by the letters A through F.

A numbering system using a base number of 16 and including the ten decimal digits (0 to 9) along with six alpha digits (A to F). Thus, a digit is available to represent each of the possible values of a 4-bit binary digit.

Same as SEXADECIMAL. A number system with a base of sixteen; also pertains to conditions, choices, or selections that have sixteen possible values or states.

Also known as Hex. A base-16 numbering system used in computer programming. The sixteen numbers in the hexadecimal system are 1-9 and the letters A-f.

A Hexadecimal is a numbering system which uses a base of 16. The first 10 digits are 0-9 and the next 6 are A-F. Hexadecimal numbers are used to define color web pages. (e.g. the hexadecimal equivalent for white is #FFFFFF.

A numeral system with 16 as its base. It is represented by 16 digits, namely 0 - 9 and A - F. For example 20 in decimal system is represented by 14 (read: "one four", NOT "fourteen") in hexadecimal system. Conversely, 2F in hexadecimal equals 2x161+15x160 or 47 in decimal system. Each digit position is equivalent with 16 raised to the power of its order from the rightmost position. The count starts at zero. MAC address and IPv6 address are written in hexadecimal format. Many programming languages also prefers hexadecimal format. This is because 1 byte (or 8 bits) can be shortened to 2 hexadecimal digits, thus makes the writing shorter. Also see binary.

a mathematical calculation that is required by hypertext markup language (HTML) to describe red, green and blue (RGB) values of color for the web.

A form of computer data format where all values are expressed as a sequence of Base 16 digits (0-9, A-F).

Hexadecimal Base 16 counting (ordinary numbers are Base 10). Many MIDI software packages represent the MIDI data in Hex, which is far more compact than the native Binary.

Is a 16 base numbering system that lists 16 sequential numbers using 1 position before adding a 2nd position. The numbers are: 0-9 representing zero through nine, and the letters A-F representing ten through fifteen (remembering 0 - to makes 16 numbers). Using this hexadecimal numbering system, the number 10 would be written as "A", 11 would be "B", ..., 15 would be "F", and 17 would be "11" which would be the start of the new 2nd position. Hexadecimal number are used in Html to specify different color values on a page. For example the color red would be written as hexadecimal "FF0000". This would be equivalent to the RGB decimal value of 255-0-0. [ Back

Referring to a number system with 16 members represented by 0 through 9 followed by A through F. Used to identify the 16 possible bit patterns of a half-byte; two hex digits represent one byte. Synonymous with hex.

Numbering system using a base of 16. A shorthand for computer programmers.

A base-16 numbering system based rather than the commonly used based 10. Numbering in base 16 has 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, G (these numbers and letters correspond to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16). The place holders in base-10 are 1's, 10's, 100's, 1000's; in base-16 numbering systems the place holders are 1's, 16's, 256's, 4,096's, etc. So 5CA means 5 256's, 12 16's, and 10 one's for a total of 1482.

Characterized by a selection, choice or condition that has sixteen possible different values or states. Pertaining to a fixed-radix numeration system in which the radix is sixteen.

The base 16 numbering system, as opposed to our decimal (base 10) system. The numerals 0-9 and letters a-f (or A-F) represent the numerals 0 through 15. In Java programs, hexadecimal numbers are preceded with 0x. These values may be converted to ANSI values to get their keystroke combination.

A number system with a base, or radix, of 16. The symbols used in this system are the decimal digits 0 through 9 and six additional digits which are generally represented as A, B, C, D, E, and F.

A hexadecimal number is a number using 16 as the base number. The first "digit" holds a place value of 16, the next 16, 16, 16, etc. This is a concept related to both software and hardware. See binary system.

When you define colors for backgrounds, links, fonts and whatever else in HTML, you can either define them with a word (i.e. "white") or the hexadecimal equivalent. The hexadecimal notation represents each RGB (red, green & blue) component of a color in two characters, 00 to FF, rather than three characters, 000 to 256. The hexadecimal equivalent of white is 000000, and black is FFFFFF. A very large GIF that contains a complete list of browser safe colors and their hexadecimal designations is here.

The base 16 numbering system used to represent binary numbers by programmers. See also binary.

Hexadecimal is an alternative number system to decimal. Okay, bear with me. here. You know how in decimal there are ten digits (0 - 9), so to express a number larger than nine, you have to use two digits. Well, hexadecimal has sixteen digits (0 - 9 and then A - F--kinda like high school), and it doesn't have to start counting over until it gets to numbers larger than sixteen. So 10 in hex equals 16 in decimal. The reason programmers use hex is that computers think in two digits, 0 and 1 (that's called binary). Since binary uses two digits, hexadecimal uses sixteen, and sixteen is a power of two, this gives hexadecimal mystical properties, which I won't take the time to explain, that basically make hex a shorter way of writing binary. That explanation kind of reminds me of the joke about fire engines.

A Base-16 notation commonly used to represent binary values in computers and coding structures, such as ASCII, EBCDIC, and ISO 646.

of or pertaining to a number system having 16 as its base

Numbers expressed in base sixteen. Integers larger than 9 are expressed as sequential letters A through F. In hexadecimal, the number ten is written A. The number sixteen is expressed as 10 - that is, one sixteen and no ones, just as 10 in the standard decimal system represents one ten and no ones. Why would anyone want to express numbers in base sixteen? Because that's how many bits there are in a 16-bit word, so using hexadecimal allowed programmers to denote a specific bit in any word as a single digit, 0 through F. Back in the days of eight-bit machines, programmers used octal, or base eight, numbers.

A base-16 numbering system consisting of the characters 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F (where A through F represent the decimal values 10 through 15). It is used in HTML for specifying color values.

A number system that uses 16 as the base. (Place value indicates powers of 16.) It uses the digits 0-9 and A-F. Used around computers because a byte (eight binary digits) easily converts to a two digit hexadecimal number. Hexadecimal numbers are often indicated with the letter H, a dollar sign, or a subscripted 16 after the number.

A base-16 data format (1 to 9 and A to F, where A is 10 and F is 15) used to represent sensor data. A byte (eight bits) is represented by two characters.

The name given to numbers to a base 16. It uses numbers 0 to 9 then A to F.

Hexadecimal numbers are numbers in base 16. Hexadecimal uses the numbers 0-9 and A, B, C, D, E, F. The letters are equivalent to the numbers 10, 11, 12, 13, 14, 15 in decimal (base 10). Hexadecimal numbers are used as a shorthand for binary.

Base 16 system, often used in computing. Counting is as follows {0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F}.

(or hex for short) Base-16 numbers made of the digits 0..9 and A..F (e.g. 08CF hex =2255).

Hexadecimal numbers are base 16 numbers that form the binary code used by computers. Each colour shown on the screen has a specific code. You don't need to know these codes if you use a browser-safe colour palette.

A numbering system that uses 16 rather than 10 as the base for representing numbers. It is therefore referred to as a base-16 numbering system. The hexadecimal system uses the digits 0 through 9 and the letters A through F (uppercase or lowercase) to represent the decimal numbers 0 through 15. For example, the hexadecimal letter D represents the decimal number 13. One hexadecimal digit is equivalent to 4 bits, and 1 byte can be expressed by two hexadecimal digits.

Pertaining to a system of numbers to the base sixteen; hexadecimal digits range from 0 (zero) through 9 (nine) and A (ten) through F (fifteen).

Hexadecimal is a base-16 number system. It is a different method of ...

The base-16 numbering system whose digits are 0 through F (the letters A through F represent the decimal numbers 10 through 15). This is often used in computer programming because it is easily converted to and from the binary (base-2) numbering system the computer itself uses.

A base 16 numbering scheme used with computers as a shorthand notation for binary information.

A numbering system which uses a base of 16. The first ten digits are 0-9 and the next six are A-F. Hexadecimal numbers are used to color web pages. For example, the hexadecimal equivalent for the color white is #FFFFFF.

A numbering system based on 16 rather than 10. Hexadecimal uses the letters A, B, C, D, E, and F along with numbers 0 to 9 to create new number combinations.

A type of math used in computer programming, base 16 instead of the normal base 10. Since there are no single-digit numbers greater than 9, those places are filled with letters, like so: 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f. In hex, the number "15" can be expressed as "e", and "100" can be expressed as "ff". The short answer "why?" is so 3 digit numbers can be expressed in 2 digits, many 5 digit numbers in 4 digits, and enormous numbers in just 8 digits. The long answer has to do with the architecture of computer chips, and that's as much as you want to know.

The base 16 number system used to describe the Red Green Blue colour levels in web images or design graphics. The number order is 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F. Three pairs of numbers are used to set colour levels. For example FF FF FF would be pure white (all colours on full). FF 00 00 would produce pure red, and 00 00 00 would produce black. The colour of this text is 66 66 66.

A numbering system that works on base 16 (decimal is base 10). Widely used in the programming world because it is easy to convert binary numbers to hexadecimal and vice-versa. 15 symbols are required to represent the hexadecimal number set - 1 2 3 4 5 6 7 8 9 A B C D E F. So "10" (decimal) converted to hexadecimal would be "A".

Base16 numbering system. The hexadecimal system is useful because it can represent every byte (8 bits) as two consecutive hexadecimal digits. It is easier for humans to read hexadecimal numbers than binary numbers. For example FF in hexadecimal is 11111111 in binary or 255 in decimal.

or Hex Code. In Hexadecimal, which means "16," each bit is a switch, 0 = off, 1 = on. See also Bit and Byte. In binary math, 1 + 1 = 3. True! Each position is worth twice the position to the right. So, the far right = 1. Next to left = 1 x 2 = 2. So a 1 there plus the right hand 1 = 1x2 + 1x1 = 3. 1+1= 3. So, 0000 = 0, 0001 = 1, 0011 = 3, and 1111 = 15 (bit positions 8 + 4 + 2 + 1), for 16 positions, 0-15, and they get represented by the number 0-9 plus the letters A-F. 1111 = 15 = F.

The numbering system that uses 16 as its base. The marks 0-9 and a-f (or equivalently A-F) represent the digits 0 through 15. In programs written in the Java programming language, hexadecimal numbers must be preceded with 0x. See also octal.

Representation of numbers using base 16.

When you define colours for backgrounds, links, fonts and whatever else in HTML, you can either define them with a word (i.e. "white") or the hexadecimal equivalent. The hexadecimal notation represents each RGB (red, green & blue) component of a colour in two characters, 00 to FF, rather than three characters, 000 to 256. The hexadecimal equivalent of white is 000000, and black is FFFFFF. Click here to see the Hex Colour Chart.

Hexadecimal refers to numbers using base 16.

A number system based on 16 digits. Hexadecimal notation — with the numbers 0 through 9 representing the first 10 digits, and the letters A through F representing the final six — is typically used in storage or memory addressing to identify each of 16 possible bit patterns.

Hexadecimal describes a base-16 number system: a system containing 16 sequential numbers as base units (including 0) before adding a new position for the next number. Hexadecimal is a convenient way to express binary numbers in modern computers in which a byte is almost always defined as containing eight binary digits.

A number system having 16 as its base. This number representation uses the digits 0-9, with their usual meaning, plus the letters A-F (or a-f) to represent hexadecimal digits with values of (decimal) 10 to 15. The far right digit counts ones, the next counts multiples of 16, then 16^2 = 256, and so on. Hexadecimal is more succinct than binary for representing bit masks, machines addresses, and other low-level constants but it is still reasonably easy to split a hex number into different bit positions. For example, the top 16 bits of a 32-bit word are the first four hex digits.

A method of representing a single alphanumeric character with a 16 numbering system, in which the first 10 digits are 0 through 9, and the last six are A through F. When a number is written in base 16, it is preceded by a dollar sign "$" (for example, $F3 is the hexadecimal representation for 243).

Base 16 notation, where the digits are - and -, with representing 10, representing 11, and so on up to for 15. Hexadecimal numbers are written in C using a leading `0x', to indicate their base. Thus, 0x12 is 18 (one times 16 plus 2).

A counting system that uses 16 digits, traditionally notated as 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F.

Hexadecimal describes a base-16 number system. That is, it describes a numbering system containing 16 sequential numbers as base units (including 0) before adding a new position for the next number. (Note that we're using "16" here as a decimal number to explain a number that would be "10" in hexadecimal.) The hexadecimal numbers are 0-9 and then use the letters A-F. We show the equivalence of binary, decimal, and hexadecimal numbers in the table below.

Hexadecimal is a system of numbering based on 16 (rather than ten like the ordinary decimal system). The normal numeric digits from 0 to 9 are augmented by the first six letters of the alphabet (A to F) in order to give the 16 different single digit numbers required by the system. Equipment manuals often give MIDI codes in hexadecimal form, but usually include a conversion table that gives hex to decimal conversions.

The hexadecimal numbering system has 16 as its base, as contrasted with the decimal system that has a base of 10. Hexadecimal refers to whole numbers in positional notation with 16 as the base. The first ten digits are represented by 0 through 9, and the last six digits represented by A, B, C, D, E, and F. Computer memory addresses are conveniently expressed in hexadecimal notation since the word length is a multiple of four. Four bits can be expressed with one hexadecimal digit. For example, 1011001010000111 binary is B287 in hexadecimal notation. A hexadecimal number is the 1-byte equivalent of an EBCDIC character.

a base-16 number, using the digits 0 through 9, and , , , , and (for 10 through 15). There are 4 bits (one nibble) to a hexadecimal digit. A byte can hold two hex digits. See binary, decimal, ASCII, EBCDIC.

A base-16 numbering system (from hexadecem, Latin for 16) particularly important in computer programming, since four bits (each consisting of a one or zero) are succinctly expressed using a single hexadecimal digit. Hexadecimal resembles decimal (base-10) numbering with the digits 0 through 9, but the decimal equivalents of 10 - 16 are represented in hexadecimal by the letters A through F. Example: the decimal number 252 is written in hexadecimal as FC.

A base 16 numbering system. The 16 hexadecimal digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F. Hexadecimal is particularly useful in computing because the 16 possible combinations of four bits can be represented by the 16 hexadecimal digits. This allows a byte to be represented by two hexadecimal digits, making it more concise and easier to read than binary machine language.

In mathematics and computer science, hexadecimal, base-, or simply hex, is a numeral system with a radix, or base, of 16, usually written using the symbols 0–9 and A–F, or a–f. For example, the decimal numeral 79, whose binary representation is 01001111, is 4F in hexadecimal (4 = 0100, F = 1111). IBM introduced the current hexadecimal system to the computing world; an earlier version, using the digits 0–9 and u–z, was introduced in 1956, and was used by the Bendix G-15 computer.
