The base 2 method of counting in which only the digits 0 and 1 are used. In this base , the number equals. This base is used in computers, since all numbers can be simply represented as a string of electrically pulsed ons and offs. In computer parlance, one binary digit is called a bit , two digits are called a crumb , four digits are called a nibble , and eight digits are called a byte.

An integer may be represented in binary in the Wolfram Language using the command BaseForm [ n , 2], and the first digits of a real number may be obtained in binary using RealDigits [ x , 2, d ]. Finally, a list of binary digits can be converted to a decimal rational number or integer using FromDigits [ l , 2]. The illustration above shows the binary numbers from 0 to 63 represented graphically Wolfram , p.

A negative number is most commonly represented in binary using the complement of the positive number , so would be written as the complement of , or This allows addition to be carried out with the usual carrying and the leftmost digit discarded, so gives. The number of times that a given binary number is divisible by 2 is given by the position of the first counting from the right. For example, is divisible by 2 twice, and is divisible by 2 zero times.

The number of times that 1, 2, OEIS A , which is the binary carry sequence. Real numbers can also be represented using binary notation by interpreting digits past the "decimal" point as negative powers of two, so the binary digits would represent the number. The sequence of binary digits for the integers , 1, Unfortunately, the storage of binary numbers in computers is not entirely standardized. Because computers store information in 8- bit bytes where a bit is a single binary digit , depending on the "word size" of the machine, numbers requiring more than 8 bits must be stored in multiple bytes.

However, a number represented as byte1 byte2 byte3 byte4 in a VAX would be read and interpreted as byte4 byte3 byte2 byte1 on a Sun. The situation is even worse for floating-point real numbers, which are represented in binary as a mantissa and characteristic , and worse still for long 8-byte reals! Binary multiplication of single bit numbers 0 or 1 is equivalent to the AND operation, as can be seen in the following multiplication table. Consider the cumulative digit sum of all binary numbers up to 1, 2, The first few terms are then 1, 2, 4, 5, 7, 9, 12, 13, 15, 17, 20, 22, This sequence in monotonic increasing left figure , but if the main asymptotic term is removed, a sequence of humped curves right figure; Trott , p.
