How to use the antilog calculator
Antilog is the inverse of log: given the log of a number, find the original number.
Formula & explanation
antilog_b(x) = b^x.
Examples
antilog₁₀(3) = 1000. antilog_e(1) = 2.718…
Frequently asked questions
- What is an antilog?
- Antilog is the inverse operation of a logarithm. If log_b(y) = x, then antilog_b(x) = b^x = y. It converts a logarithm back to the original number.
- What base should I use?
- Use base 10 for common logarithms (log), and base e (≈ 2.71828) for natural logarithms (ln). Base 2 is common in computer science.
- How is antilog different from an exponent?
- They are the same operation: antilog_b(x) = b^x. The term 'antilog' is used specifically in the context of reversing a logarithm calculation.
- What is antilog of 0?
- Antilog_b(0) = b^0 = 1 for any base b. The logarithm of 1 is always 0 in any base, so the antilog of 0 is always 1.
