Webster Dictionary

  1. Logarithmnoun

    one of a class of auxiliary numbers, devised by John Napier, of Merchiston, Scotland (1550-1617), to abridge arithmetical calculations, by the use of addition and subtraction in place of multiplication and division

    Etymology: [Gr. lo`gos word, account, proportion + 'ariqmo`s number: cf. F. logarithme.]

Freebase

  1. Logarithm

    The logarithm of a number is the exponent to which another fixed value, the base, must be raised to produce that number. For example, the logarithm of 1000 to base 10 is 3, because 1000 is 10 to the power 3: 1000 = 10 × 10 × 10 = 10³. More generally, if x = b, then y is the logarithm of x to base b, and is written y = logb(x), so log10 = 3. The logarithm to base b = 10 is called the common logarithm and has many applications in science and engineering. The natural logarithm has the constant e as its base; its use is widespread in pure mathematics, especially calculus. The binary logarithm uses base b = 2 and is prominent in computer science. Logarithms were introduced by John Napier in the early 17th century as a means to simplify calculations. They were rapidly adopted by navigators, scientists, engineers, and others to perform computations more easily, using slide rules and logarithm tables. Tedious multi-digit multiplication steps can be replaced by table look-ups and simpler addition because of the fact—important in its own right—that the logarithm of a product is the sum of the logarithms of the factors: The present-day notion of logarithms comes from Leonhard Euler, who connected them to the exponential function in the 18th century.

Chambers 20th Century Dictionary

  1. Logarithm

    log′a-rithm, n. (of a number) the power to which another given number must be raised in order that it may equal the former number: one of a series of numbers having a certain relation to the series of natural numbers by means of which many arithmetical operations are simplified.—adjs. Logarith′mic, -al, pertaining to, or consisting of, logarithms.—adv. Logarith′mically. [Gr. logos, ratio, arithmos, number.]

The Nuttall Encyclopedia

  1. Logarithm

    the exponent of the power to which a fixed number, called the base, must be raised to produce a certain given number.

The Standard Electrical Dictionary

  1. Logarithm

    The exponent of the power to which it is necessary to raise a fixed number to produce a given number. The fixed number is the base of the system. There are two systems; one, called the ordinary system, has 10 for its base, the other, called the Naperian system, has 2.71828 for its base. The latter are also termed hyperbolic logarithms, and are only used in special calculations.
