Antilogarithm is the inverse function of logarithm, defined such that n is antilogarithm of a if log n = а.
The antilogarithm in base b of a is therefore the value of b to the power of a
Well, since we have Logarithm calculator, we probably should have antilogarithm calculator, albeit very easy one.
And, by the way, the default value for logarithm base is Euler's number - for convenience.
