What is an antilogarithm?

An antilogarithm, also called inverse logarithm, is the inverse of the logarithm operation. It is exactly the same as exponentiation, that is - to raise a number to a given power.

A strict definition for the antilog function is: f(x) = bx, which is exactly the inverse of logb(x).

For example, the inverse logarithm of log264 is 26 since 2 x 2 x 2 x 2 x 2 x 2 = 64. Thus antilog(64) = 26 when using a base of 2.

Havign a handy antilog calculator means you no longer need to rely on log tables, since you can quickly calculate antilogarithms using this calculator.
