- Antilogarithm — A number whose logarithm value in a given base is equal to a considered number; the inverse operation of taking a logarithm, structurally representing the raising of the base to the power indicated by the logarithm. In a functional sense, if log base b of x equals y, then the antilogarithm of y in base b equals x, historically used in complex numerical calculations via tables.
