CLOG10(3)                 Linux Programmer's Manual                CLOG10(3)

NAME         top

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

SYNOPSIS         top

       #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);
       Link with -lm.

DESCRIPTION         top

       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         top

       These functions first appeared in glibc in version 2.1.
