What is Antilog? Definition, Formula, and Examples

Antilog (short for "anti-logarithm") is a mathematical function that is the inverse of the logarithmic function. In other words, it undoes the effect of taking the logarithm of a number.

The antilog of a number x is the number y such that y is the logarithm of x. In other words, y = log(x).

For example, if we take the logarithm of 100, we get 2:

log(100) = 2

So, the antilog of 2 is 100:

antilog(2) = 100

Antilog is not a standard mathematical function, but it can be useful in certain contexts where you need to undo the effect of taking the logarithm of a number. For example, if you have a formula that involves taking the logarithm of a quantity, and then you want to reverse the operation and find the original quantity, you can use antilog to do so.
