double complex clog(double complex z);
float complex clogf(float complex z);
long double complex clogl(long double complex z);
The functions calculate the complex natural logarithm of z, with a branch cut along the negative real axis.
z - the complex number,
The complex natural logarithm value, in the range of a strip mathematically unbounded along the real axis and in the interval [-iπ, +iπ] along the imaginary axis.
