NAME

clog10, clog10f, clog10l - bas-10 logarithm of a complex number  

LIBRARY

Math library (libm,~-lm)  

SYNOPSIS

#define _GNU_SOURCE         /* See feature_test_macros(7) */
#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) or equally: log10(cabs(c)) + I * carg(c) / log(10) The other functions perform the same task for float and long double. Note that z close to zero will cause an overflow.
