Understanding Complex Logarithms

The complex logarithm extends the concept of logarithms to complex numbers. For a complex number z = x + iy, and a base b, the complex logarithm logb(z) is a complex number w such that bw = z.

Due to the periodic nature of complex exponentials, the complex logarithm is multi-valued. This calculator provides the principal value of the complex logarithm.

Formula: If z = re is the polar form of a complex number, then logb(z) = logb(r) + i(θ + 2πk) / ln(b), for any integer k. For the principal value, we take k = 0 and the principal value of θ in the interval (-π, π].
