clog10(3)                                             Library Functions Manual                                            clog10(3)

NAME
       clog10, clog10f, clog10l - base-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.

VERSIONS
       These functions first appeared in glibc 2.1.
