CLOG2(3) complex math routines CLOG2(3)
NAME
clog2, clog2f, clog2l - base-2 logarithm of a complex number
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.
CONFORMING TO
These function names are reserved for future use in C99.
AVAILABILITY
Not yet in glibc, as at version 2.4.
