# Antilog function

Use the Minitab calculator to calculate the antilog of a number using base 10. The antilog is the inverse of the log base 10. You can use the antilog to calculate the original values of data that were previously transformed using a log base 10.

To use this function, choose Calc > Calculator.

Calculates 10n, where n is the specified number. For example, the antilog of 2 is 102 = 100.

###### Note

Some calculators define the Antilog function using a base other than 10, such as base e. In Minitab, the inverse function for the natural logarithm is the Exponential function.

## Syntax

ANTILOG(number)

In number, specify the value or column of values. Minitab calculates 10n.

## Example

Calculator expression Result
ANTILOG(3) 1000

## Uses

The antilog is the inverse of the log base 10. You can use the antilog to calculate the original values of data that were previously transformed using a log base 10. For example, if an original data value is 18,349, the log base 10 of 18,349 ≈ 4.2636124. To transform 4.2636124 back to the original value, use antilog (4.2636124) ≈ 18,349.
