Find 10ˣ, eˣ or a custom positive base raised to x. Start simply, then adjust optional base and display settings when needed.
01 / YOUR EXPONENT
Antilog raises a base to your exponent. Start with base 10, or open Advanced for natural and custom bases.
02 / RESULT
Enter an exponent and calculate. Base 10 is selected by default.
03 / QUICK EXPLANATION
If log₁₀(y) = x, then y = 10ˣ. For example, log₁₀(100) = 2, so the antilog of 2 is 10² = 100. Natural antilog reverses ln(y) using eˣ.
A custom logarithm base must be positive and different from 1. Negative exponents give reciprocals: 10⁻² = 1/100 = 0.01. Any valid base raised to zero gives 1.
Very large or small results use scientific notation: 1e+100 means 1 × 10¹⁰⁰. Calculations use JavaScript double precision, not arbitrary-precision arithmetic. Overflow and zero-underflow are reported as errors; reduced-precision subnormal values carry a warning.

An antilog reverses a logarithm. If log base b of y equals x, then y = b raised to x. For base 10, the antilog of 2 is 100.
Base 10 is selected by default. Advanced options include natural base e and any finite positive custom base other than 1. A base of 1 does not define an invertible logarithm.
Yes. Negative exponents produce reciprocals, decimal exponents are supported, and any valid base raised to zero equals 1. Finite scientific-notation inputs are accepted.
No. Display settings round only the displayed and copied result. Calculations use JavaScript double precision; requesting more digits cannot create arbitrary-precision accuracy.
If the result exceeds JavaScript's finite range or rounds to zero, an error replaces the result. Nonzero subnormal values and values that round indistinguishably to 1 receive precision warnings.
Scientific notation keeps very large and small results readable: 1e+100 means 1 × 10 to the power 100. Automatic notation switches for results at least 1e9 or below 1e-6; you can also request it for all results.
