AntiLog Calculator

Last Updated : 9 Mar, 2026

The antilogarithm, often abbreviated as "antilog," is the inverse operation of the logarithm.

Steps to Use an Antilog Calculator

To use an antilog calculator, we can use the following steps:

Step 1: Select the required base for the antilogarithm calculation — either Base 10 (10ˣ) or Base e (eˣ).

Step 2: Enter the value (x) for which you want to calculate the antilogarithm in the Input Value field.

Step 3: Click the “Calculate Result” button or press the Enter key to start the calculation.

Step 4: View the calculated antilogarithm displayed instantly in the Result section. You can also copy the result using the copy button.

Definition ,

Mathematically, if logb(x) = y, then the antilogarithm of y with base b, denoted as antilogb(y), equals x.

For example, if log10(100) = 2, then the antilogarithm of 2 with base 10 (antilog10(2)) equals 100.

Antilog Table

  • An antilog table is a reference tool used in mathematics, particularly in the context of logarithms.
  • It provides a quick way to find the antilogarithm (or inverse logarithm) of a given logarithm.
  • The antilogarithm of a number x is simply 10 raised to the power of x, denoted as 10x.

Values of Antilog

Values of some common antilogarithms are listed in the following table:

Number (x)Antilogarithm (10x)
01
110
2100
31000
410000
5100000
61000000
710000000
8100000000
91000000000
1010000000000

Antilog Vs Log

Antilog and log are two sides of the same mathematical concept, with logarithms representing the power to which a base must be raised to produce a given number, while antilogarithms, conversely, give the result of raising the base to a certain power. We can see the difference in values for both log and antilog in the following table for a better understanding of this relation.

Number (x)Logarithm (log10(x))Antilogarithm (10x)
1010 = 10
1011010 = 10,000,000,000
100210100

1000041010000
0.1-110-1 = 0.1
0.01-210-2 = 0.01
0.001-310-3 = 0.001
0.0001-410-4 = 0.0001
