NAME¶

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

LIBRARY¶

Math library (libm, -lm)

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);

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.
