Antilog value:


The logarithm, expressed in mathematics as:

logb(N) = x is the exponent of the power of a given base 2, 10 and e (Neperian number).

Example: log10(N) (100) = 2.

Menas base (b) is 10 and number (N) is 100.

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 10 raised to the logarithm (exponent).

Example: antilog10(2) = 100..
