The antilog, also known as the inverse logarithm, is a mathematical operation that can be used to reverse the effect of a logarithm. In Excel, the antilog can be calculated using the EXP function, which returns the exponential value of a given number. In this Excel tutorial, you will learn how to handle antilog in Excel.
What is antilog?
The exponential function, denoted by e^x, is the inverse of the natural logarithm function. The antilog of a number is simply the exponential value of the logarithm of that number. In other words, if y = log(x), then x = e^y.
Sometimes, showing is better than describing. Here is the equation which will show you what is antilog.
antilogxY = Xy
I hope you understand now.
How to calculate antilog in Excel?
There are different types of logarithms in Excel. To calculate antilog, you need to calculate the opposite of the logarithm calculations.
Antilog of natural logarithm
Antilog ln formula is =EXP(B2) in my example.
So to calculate the antilog of a natural logarithm, you need to calculate the power of the number.
It’s important to note that the EXP function in Excel uses a natural logarithm base, which is denoted by e. This means that the antilog of a number in Excel is calculated using the exponential function with base e.
In some cases, you may need to use a different logarithm base, such as base 10.
Log base 10
Antilog of log 10
Antilog log10 formula is =10^B5 in my example.
To calculate the inverse of log base 10 you need to power 10 to the base of the result of log10.
Antilog log formula is =B9^B5 in my example.
To get the antilog of a logarithm, you need to power base the result.
As you can see, in every example, calculations work because antilog is equal to the number.
Here's the link to the antilog spreadsheet, which will help you understand.
In conclusion, the antilog is a useful mathematical operation that can be used to reverse the effect of a logarithm. In Excel, the antilog can be easily calculated using the EXP function, which returns the exponential value of a given number. By following the steps outlined in this guide, you can use Excel to find the antilog of logarithm values with base e or base 10, depending on your needs.
