clog10, clog10f, clog10l − base-10 logarithm of a complex number

#include <complex.h>

double complex clog10(double complexz);

float complex clog10f(float complex z);

long double complex clog10l(long double complexz);

The logarithm is defined as log10(cabs(z))+I*carg(z). Please note that z close to zero will cause an overflow.
