- complex natural logarithm functions
c99 [ flag... ] file... -lm [ library... ] #include <complex.h> double complex clog(double complex z);
float complex clogf(float complex z);
long double complex clogl(long double complex z);
These functions compute the complex natural (base e) logarithm of z, with a branch cut along the negative real axis.
These functions return the complex natural logarithm value, in the range of a strip mathematically unbounded along the real axis and in the interval [ -i , +i ] along the imaginary axis.
