NAME

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

LIBRARY

Math library (libm, -lm)

SYNOPSIS

bash

#define _GNU_SOURCE\n         /* See feature_test_macros(7) */
\n#include <complex.h>

bash

double complex clog10(double complex \nz\n);\n
\nfloat complex clog10f(float complex \nz\n);\n
\nlong double complex clog10l(long double complex \nz\n);

DESCRIPTION

The call clog10(z) is equivalent to:

bash

clog(z)/log(10)

or equally:

bash

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.
