Formula & Methodology
The formula to calculate the antilog of a negative number is:
antilog(-x) = 10^(-x)
Where x is the negative number and 10 is the base of the common logarithm.
Real-World Examples
Example 1: Stock Prices
In finance, the antilog of a negative number can be used to calculate stock prices based on logarithmic returns.
If the logarithmic return is -0.05, the stock price change is:
antilog(-0.05) = 10^(-0.05) ≈ -0.95
Example 2: Decibel Levels
In acoustics, the antilog of a negative number can be used to convert decibel levels to sound pressure levels.
If the decibel level is -20 dB, the sound pressure level is:
antilog(-20) = 10^(-20) ≈ 0.01
Example 3: pH Levels
In chemistry, the antilog of a negative number can be used to convert pH levels to hydrogen ion concentrations.
If the pH level is -1, the hydrogen ion concentration is:
antilog(-1) = 10^(-1) = 0.1

- Consider using a scientific calculator or software for more complex calculations.
Interactive FAQ
What is the difference between antilog and log functions?
The antilog function reverses the effect of a logarithm, while the log function calculates the power to which a base must be raised to produce a given number.
Why is the antilog of a negative number less than 1?
The antilog of a negative number is less than 1 because the base of the common logarithm (10) is greater than 1, and raising it to a negative power results in a fraction between 0 and 1.
