# Logarithm & Antilogarithm

The logarithm, expressed in mathematics as **log _{b}(N) = x ** is the
exponent of the power of a given base, usually 10 and the Neperian number (e). Example:

**log**The logarithm can be converted in the exponential form:

_{10}(100) = 2.**b**, where x is the logarithm of N in the base b.

^{x}= NThe inverse logarithm or antilogarithm expressed in mathematics as

**antilog**is the power of a given base usually, 10 and Neperian number (e) raised to the logarithm (exponent). Example: antilog

_{b}(x) = N_{10}(2) = 100.

Use the point as decimal separator. Ex. For the number 15,151.42, enter 15151.42.
