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.
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.
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.
Learn about a binary encoding method for decimal digits that packs three digits into ten bits and allows compression or expansion to BCD. See the encoding rules, history and applications of densely packed decimal.
Binary code is a system of representing text, instructions or data using two symbols, usually 0 and 1. Learn about the origin of binary code, its applications in computing and telecommunications, and other forms of binary code such as Braille and bagua.
A binary decoder is a logic circuit that converts binary information from multiple inputs to unique outputs. Learn about different types of decoders, such as 1-of-n, code translators, and binary to unary decoders, and their applications.
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.
Excess-3, also known as XS-3, is a self-complementary binary-coded decimal (BCD) code and numeral system. It is used in some older computers, calculators and cash registers, and has advantages for subtraction and carry detection.
