Formula

The antilogarithm (or inverse logarithm) is the reverse operation of a logarithm. If logₐ(x) = y, then antilogₐ(y) = a^y = x. For example, antilog₁₀(2) = 10² = 100.

antilogₐ(N) = a^N

Percentage: The percentage value you want to apply

Number: The original number or value

Result: The calculated result

How It Works

1Enter the number (the logarithm value).
2Enter the base.
3Click Calculate to compute the antilog.

Examples

Antilog base 10 of 2

1.Enter number=2, base=10.
2.Calculate: 10² = 100.
3.Result: 100.

Result: 100

Antilog base e of 1

1.Enter number=1, base=e≈2.71828.
2.Calculate: e¹ = 2.71828.
3.Result: 2.71828.

Result: 2.71828

Frequently Asked Questions

A logarithm finds the exponent needed to produce a number from a given base. An antilog reverses this by raising the base to that exponent.

Common bases are 10 (common log), e ≈ 2.71828 (natural log), and 2 (binary log). Use the base that matches your original logarithm.

Yes, any positive base other than 1 is supported.

Antilogs are used in chemistry (pH calculations), physics (decibels), finance (compound interest), and data science (log-transformed data reversal).

The antilog of 0 with any base is 1, since any number raised to the power of 0 equals 1.
