In computing and electronic systems, binary-coded decimal BCD is a class of binary encodings of decimal numbers where each decimal digit is represented by a fixed number of bitsusually four or eight. Special bit patterns are sometimes used for a sign or for other indications e. In byte-oriented systems i. The precise 4-bit encoding may vary however, for technical reasons, see Excess-3 for instance.
The ten states representing a BCD decimal digit are sometimes called tetrades for the nibble typically needed to hold them also known as tetrade with those don’t care -states unused named pseudo-tetrad e s or pseudo-decimal digit. BCD’s main virtue is its more accurate representation and rounding of decimal quantities as well as an ease of conversion into human-readable representations, in comparison to binary positional systems.
BCD’s principal drawbacks are a small increase in the complexity contdor the circuits needed to implement basic arithmetics and a slightly less dense storage. Different computer manufacturers, and even different product lines from the same manufacturer, often had their own variants, and sometimes included unique characters.
Other six-bit encodings with completely different mappings, such as Fieldata and Transcodeare sometimes incorrectly termed BCD.

Many variants of BCD encode the characters ‘0’ through ‘9’ as the corresponding binary values. Technically, binary-coded decimal describes the encoding of decimal numbers where each decimal digit is represented by cnotador fixed number of bits, usually four. With the introduction of the IBM card inIBM created a code capable of representing alphanumeric information, later adopted by other conatdor. This code represented the numbers by a single punch, and used multiple punches for upper-case letters and special characters.
After returning to Puerto Rico, he started working in advertising.
Inhe decided to dedicate himself to music, releasing his first eponymous album the following year. Beyond that, he has released two more albums, the last one being Mucha Cosa Buenain Azteca 7’s programming is available in HD and is available where affiliates are broadcasting in digital television. Alberto Contador Velasco Spanish pronunciation: He was the winner of contacor Tour de France with the Discovery Channel team.
He initially also won the Tour de France with this team, and the Giro d’Italia with team Saxo Bank-SunGard, only to be stripped of these titles later having been found guilty of a doping offence. After being widely expected to lose his tenuous lead in the Tour de France in that race’s final individual time trialContador has become a more accomplished time trialist, with several victories in the discipline.
He has earned a reputation as an all-rounder, 74s90 cyclist who excels in all aspects of stage racing which are needed for high places in the general classification. Create your page here.
