# clog(3) [centos man page]

```CLOG(3) 						     Linux Programmer's Manual							   CLOG(3)

NAME
clog, clogf, clogl - natural logarithm of a complex number

SYNOPSIS
#include <complex.h>

double complex clog(double complex z);
float complex clogf(float complex z);
long double complex clogl(long double complex z);

DESCRIPTION
The  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.

VERSIONS
These functions first appeared in glibc in version 2.1.

CONFORMING TO
C99.
