Antilog Calculator
The Antilog Calculator helps you calculate the inverse of a logarithm, also known as the antilogarithm. By entering a logarithm value and selecting a base, you can instantly determine the original number. This calculator supports common logarithms (base 10), natural logarithms (base e), binary logarithms (base 2), and custom bases.
What Is an Antilog?
An antilogarithm is the inverse operation of a logarithm. If a logarithm tells you the exponent needed to produce a number, the antilog calculates the original number from that exponent.
For example:
log₁₀(100) = 2
Therefore:
Antilog₁₀(2) = 100
Antilog Formula
Antilog = bx
Where:
- b = Base of the logarithm
- x = Logarithm value
- Result = Original number
Examples
Example 1
Antilog₁₀(3)
= 10³
= 1000
Example 2
Antilog₂(8)
= 2⁸
= 256
Example 3
Antiloge(2)
= e²
≈ 7.389056
