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

Math library (`libm`

, `-lm`

)

```
#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);
```

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.
