n

1. a single symbol or character representing a quantity. n 2. a finger or toe.

[Etymology: Lat: ‘finger’] A numeric character: 1, 2,…, 9, also 0 and, in hexadecimal notation, the letters A, B,…, F standing beyond 9. Hence the measure for ‘length’ of a number, e.g. 1 357 has a length of four digits and is a four-digit number. In computer contexts the length may include leading zeros.

All computers work fundamentally in binary mode, with information represented by a succession of on/off or equivalent pulses. Mathematically these are represented, in binary notation, by strings of 0's and 1's, referred to as binary digits or bits. Various computers of the 1960s and 1970s had their storage designed with bits grouped into decimal or other digits, some designs even allowing for program-specified mixing to deal with the problems of non-decimal currencies and measurement units. Partly through that and partly through the rigours of methodical translation of binary to decimal for output, the word ‘digit’ came from obscurity into relatively common usage. (However, many people, unfortunately, still refer to a seven-digit telephone number as having seven ‘numbers’, and to its first digit as being its ‘first number’.)

Most modern computers allow numbers to be stored and arithmetically processed internally in a purely binary form, in a decimal form using four bits per digit, and in an 8-bit character form (the byte) that encompasses alphabetic and punctuation characters along with the familiar decimal digits. (See also real number; floating-point number.)

length Classically a sixteenth of a foot, or a twenty-fourth of a cubit.

astrophysics As used in expressing the amount of overlap of the Sun and the Moon in an eclipse, a digit represents half the length of the apparent diameter (i.e. a radius length), the two objects being virtually the same apparent size from Earth.

One of the five fingers on each hand or five toes on each foot.

1. a toe in cats, dogs and chickens, a foot in the horse, a claw or cleat in cattle, sheep, goats and pigs. Called also a cleat in sheep.
2. any of the ten numerals in the series 0 to 9.

IN BRIEF: Any number from 0 to 9. Also: A finger or toe.
