Antilog Calculator

Calculate the antilogarithm (inverse logarithm) of any number with a specified base. The antilog is the inverse operation of a logarithm, where antilog_b(x) = b^x.

What is an Antilog?

The antilog (antilogarithm) is the inverse function of a logarithm. If log_b(y) = x, then antilog_b(x) = y. In other words, the antilog of x with base b is simply b raised to the power of x.

Formula

The antilog formula is:

• antilog_b(x) = b^x
• Where b is the base and x is the logarithm value

Common Uses

• Base 10: Used in common logarithms, pH calculations, decibel measurements
• Base e (natural): Used in exponential growth, continuous compounding, natural sciences
• Base 2: Used in computer science, information theory, binary calculations

Examples

• antilog₁₀(2) = 10² = 100
• antilog₁₀(3) = 10³ = 1000
• antilog_e(1) = e¹ ≈ 2.718
• antilog₂(8) = 2⁸ = 256
