If you are looking to calculate the inverse logarithm function, then the antilog calculator is the perfect tool for you. With this calculator, you can calculate any number with an arbitrary base’s antilogarithm – including a natural antilog or any other number.

Are you still stuck on the word ‘antilogarithm’ and what it means? Below, you can find out what it is and how it works.

What is a Logarithm?

Explaining it as simply as possible, a logarithm is the inverse function to exponentiation ratio. The logarithm of a number (x) is the exponent, which means you must raise the base (b) to produce that number (x). It looks something like this: 

Y= logbx

You would use the logarithmic scale, which is a nonlinear scale for a variety of values, for use with the ratio of logarithms. This scale is used not only in math, but science too. 

You could also use it for:
  •	Measuring the strength of an earthquake
  •	Number theory
  •	Psychology 
  •	pH scales in chemistry
  •	checking sound intensity in acoustics

Antilogarithm and Calculating it

In essence, the antilogarithm is the exponentiation. If you were to calculate the antilog of a number (x) you have to raise b, the logarithm base, to the power of y. B usually is either ten or E. 

It looks like this:

x = logb-1(y) = bY

Remember, both antilog and log are inverse functions, which creates: 
X = bY = blogbx, 
and y = logbx = logb(by)

An Inverse Log Calculation Example

So you understand an inverse log calculation in theory, but why not try an example? Follow the steps below.

  1.	Choose a number of which you will be finding the antilogarithm. For the example, we will use 5. 
  2.	Enter your base into the antilog calculator so you can get the natural answer. Alternatively, you can type “e.” 
  3.	The antilog value will appear automatically. It’s 148.413.
