NAME         top

       clog2, clog2f, clog2l - base-2 logarithm of a complex number

LIBRARY         top

       Math library (libm, -lm)

SYNOPSIS         top

       #include <complex.h>

       double complex clog2(double complex z);
       float complex clog2f(float complex z);
       long double complex clog2l(long double complex z);

DESCRIPTION         top

       The call clog2(z) is equivalent to clog(z)/log(2).

       The other functions perform the same task for float and long
       double.

       Note that z close to zero will cause an overflow.

STANDARDS         top

       None.

       Not yet in glibc, as at glibc 2.19.
