# clog(3m) [sunos man page]

```clog(3M)						  Mathematical Library Functions						  clog(3M)

NAME
clog, clogf, clogl - complex natural logarithm functions

SYNOPSIS
cc [ 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.

## new here

Didn't want to clog the other boards lol but just came through to say whats up and I'm new here and you guys have already helped me out. Great supplement to textbooks :)

## Project Euler

Some might already have guessed it: i am as much mathematically challenged as i am mathematically inclined.(*) This old (and largely unresponded) love of mine fell mostly short in the daily work as a programmer but was ignored completely in my work as a systems administrator. To my utter delight...
