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