Logarithm vs. Antilogarithm

Logarithmnoun

(mathematics) For a number x, the power to which a given base number must be raised in order to obtain x. Written \log_b x. For example, \log_{10} 1000 = 3 because 10^3 = 1000 and \log_2 16 = 4 because 2^4 = 16.

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.

Logarithmnoun

the exponent required to produce a given number

Logarithm

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.

Antilogarithmnoun

(mathematics) The number of which a given number is the logarithm (to a given base).

Antilogarithmnoun

The number corresponding to a logarithm. The word has been sometimes, though rarely, used to denote the complement of a given logarithm; also the logarithmic cosine corresponding to a given logarithmic sine.

Antilogarithmnoun

the number of which a given number is the logarithm
