CLOG(3) Linux Programmer's Manual CLOG(3)NAMEclog, clogf, clogl - natural logarithm of a complex numberSYNOPSIS#include <complex.h> double complex clog(double complex z); float complex clogf(float complex z); long double complex clogl(long double complex z); Link with -lm.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]. One has: clog(z) = log(cabs(z)) + I * carg(z) Note that z close to zero will cause an overflow.VERSIONSThese functions first appeared in glibc in version 2.1.CONFORMING TOC99.SEE ALSOcabs(3), cexp(3), clog10(3), complex(7)COLOPHONThis page is part of release 3.25 of the Linux man-pages project.
