NAME

clog, clogf, clogl - complex natural logarithm functions  

SYNOPSIS

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);  

DESCRIPTION

These functions compute the complex natural (base e) logarithm of z, with a branch cut along the negative real axis.  

RETURN VALUES

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.  

ERRORS

No errors are defined.
