**#include <complex.h>**

**double complex clog10(double complex**

*z*

**float complex clog10f(float complex**

*z*

**);**

**long double complex clog10l(long double complex**

*z*

**);**

# DESCRIPTION

The call*clog10(z)*is equivalent to

*clog(z)/log(10)*. The other functions perform the same task for

*float*and
