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 $x$ is the antilogarithm of $y$ base $b$.
Symbol
The symbol used to denote the antilogarithm of $y$ to base $b$ is $\map {\operatorname {alog}_b} y$.
Also known as
The shortened form antilog is frequently seen for antilogarithm.
