Binary-coded decimal (BCD) is a binary encoding of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Learn about the different types of BCD, their advantages and disadvantages, and their applications in computing and electronic systems.
BCD is a family of six-bit character codes that represent numerals, uppercase Latin letters, and some special and control characters. It was used in early computers and punched cards, and has many variants with different mappings and assignments.
FatWallet was a website that allowed users to post deals and rebate offers on products and services, especially electronics. It was shut down in 2017 by its owner Rakuten, after facing legal disputes with retailers over price information.
Chen–Ho encoding is a memory-efficient alternate system of binary encoding for decimal digits.. The traditional system of binary encoding for decimal digits, known as binary-coded decimal (BCD), uses four bits to encode each digit, resulting in significant wastage of binary data bandwidth (since four bits can store 16 states and are being used to store only 10), [1] even when using packed BCD.
The Intel BCD opcodes are a set of six x86 instructions that operate with binary-coded decimal numbers. The radix used for the representation of numbers in the x86 processors is 2. This is called a binary numeral system .
Aiken code, also known as 2421 code, is a complementary binary-coded decimal (BCD) code developed by Howard Hathaway Aiken. It is used in digital clocks, pocket calculators and similar devices.
Double dabble is a computer science algorithm that converts binary numbers into binary-coded decimal (BCD) notation. It involves shifting, adding and incrementing the BCD digits based on the original binary bits.
A two-out-of-five code is a constant-weight code that represents decimal digits using five bits. It is used in barcodes, telephony, and computer arithmetic. Learn the weights, encodings, and examples of this code.
