man:clog10f

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

NAME

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

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);
     Link with -lm.

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 in version 2.1.
