NAME

6       clog10, clog10f, clog10l - base-10 logarithm of a complex number
7

SYNOPSIS

9       #define _GNU_SOURCE         /* See feature_test_macros(7) */
10       #include <complex.h>
11
12       double complex clog10(double complex z);
13       float complex clog10f(float complex z);
14       long double complex clog10l(long double complex z);
15
16       Link with -lm.

DESCRIPTION

19       The call clog10(z) is equivalent to:
20
21           clog(z)/log(10)
22
23       or equally:
24
25           log10(cabs(c)) + I * carg(c) / log(10)
26
27       The other functions perform the same task for float and long double.
28
29       Note that z close to zero will cause an overflow.
