WitrynaA logarithm is the inverse of the exponential function. Specifically, a logarithm is the power to which a number (the base) must be raised to produce a given number. For … WitrynaLogarithm is a multivalued function: for each x there is an infinite number of z such that 10**z = x. The convention is to return the z whose imaginary part lies in (-pi, pi]. For real-valued input data types, log10 always returns real output.

The exponential function can be extended to a function which gives a complex number as e for any arbitrary complex number z; simply use the infinite series with x=z complex. This exponential function can be inverted to form a complex logarithm that exhibits most of the properties of the ordinary logarithm. There are two difficulties involved: no x has e = 0; and it turns out that e = 1 = e .
