NAMEclog, clogf, clogl - natural logarithm of a complex number
double complex clog(double complex z);
float complex clogf(float complex z);
long double complex clogl(long double complex z);
DESCRIPTIONThe logarithm clog() is the inverse function of the exponential cexp(3). Thus, if y = clog(z), then z = cexp(y). The imaginary part of y is chosen in the interval [-pi,pi].
clog(z) = log(cabs(z)) + I * carg(z)
VERSIONSThese functions first appeared in glibc in version 2.1.
