NAME

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

LIBRARY

9       Math library (libm, -lm)
10

SYNOPSIS

12       #define _GNU_SOURCE         /* See feature_test_macros(7) */
13       #include <complex.h>
14
15       double complex clog10(double complex z);
16       float complex clog10f(float complex z);
17       long double complex clog10l(long double complex z);
18

DESCRIPTION

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