NAME

6       clog2, clog2f, clog2l - base-2 logarithm of a complex number
7

LIBRARY

9       Math library (libm, -lm)
10

SYNOPSIS

12       #include <complex.h>
13
14       double complex clog2(double complex z);
15       float complex clog2f(float complex z);
16       long double complex clog2l(long double complex z);
17

DESCRIPTION

19       The call clog2(z) is equivalent to clog(z)/log(2).
20
21       The other functions perform the same task for float and long double.
22
23       Note that z close to zero will cause an overflow.
