clog10, clog10f, clog10l - base-10 logarithm of a complex number
#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
.
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.
These functions first appeared in glibc in version 2.1.
