clog2, clog2f, clog2l - base-2 logarithm of a complex number
#include <complex.h> double complex clog2(double complex z); float complex clog2f(float complex z); long double complex clog2l(long double complex z);
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.
These function names are reserved for future use in C99.
Not yet in glibc, as at version 2.8.
