#define _GNU_SOURCE /* See feature_test_macros(7) */
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). The other func-
tions 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.
This function is a GNU extension. It is reserved for future use in
cabs(3), cexp(3), clog(3), clog2(3), complex(7)
