A binary number is a number expressed in the base-2 numeral system, using only two symbols: 0 and 1. Learn about the origins and applications of binary numbers in various cultures and fields, from ancient Egypt and China to modern computers and cryptography.
Octal is a numeral system with eight as the base, where each place is a power of eight. Learn how to convert octal to decimal, hexadecimal and binary, and the usage of octal in various cultures and languages.
Learn how computers represent numeric values in binary, octal and hexadecimal systems. Find out the definitions and examples of bits, bytes, nibbles and other terms related to computer number formats.
Learn about the history and features of positional notation, a numeral system that uses the position of digits to determine their value. Compare different bases, such as decimal, binary, and hexadecimal, and their applications in mathematics and computing.
Base64 is a group of schemes that transforms binary data into a sequence of 64 printable characters. Learn the design, alphabet, examples, and variants of Base64, and how it is used for data transfer and web applications.
In computing, octuple precision is a binary floating-point-based computer number format that occupies 32 bytes (256 bits) in computer memory.This 256-bit octuple precision is for applications requiring results in higher than quadruple precision.
The standard requires operations to convert between basic formats and external character sequence formats. [57] Conversions to and from a decimal character format are required for all formats. Conversion to an external character sequence must be such that conversion back using round to nearest, ties to even will recover the original number.
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.
