clog10(3) Library Functions Manual clog10(3)
clog10, clog10f, clog10l - base-10 logarithm of a complex number
Math library (libm, -lm)
#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);
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.
For an explanation of the terms used in this section, see
attributes(7).
