логарифм комплексного числа по основанию 10 (base-10 logarithm of a complex number)
Имя (Name)
clog10, clog10f, clog10l - base-10 logarithm of a complex number
Синопсис (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.
Описание (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.
