NAME

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

LIBRARY

       Math library (libm, -lm)

SYNOPSIS

       #include <complex.h>

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

DESCRIPTION

       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

       None.

HISTORY

       These function names are reserved for future use in C99.
