Logarithm and Antilogarithm


The logarithm, expressed in mathematics as logb(N) = x is the exponent of the power of a given base, usually 10 and the Neperian number (e). Example: log10(100) = 2. The logarithm can be converted in the exponential form: bx = N, where x is the logarithm of N in the base b.
The inverse logarithm or antilogarithm expressed in mathematics as antilogb(x) = N is the power of a given base usually, 10 and Neperian number (e) raised to the logarithm (exponent). Example: antilog10(2) = 100.
Use the point as decimal separator. Ex. For the number 15,151.42, enter 15151.42; enter the requested data and the result will be displayed automatically after you click "Calculate".
