Definition:Antilogarithm

Definition

Let $x \in \R_{>0}$ be a strictly positive real number.

Let $b \in \R_{>1}$ be a real number which is greater than $1$.

Let $y = \log_b x$ be the logarithm of $x$ base $b$.

Then the antilogarithm of $y$ base $b$ is:

$\operatorname {alog}_b y = x$

Also known as

The shortened form antilog is frequently seen.
