clog2(3) Library Functions Manual clog2(3)
clog2, clog2f, clog2l - base-2 logarithm of a complex number
Math library (libm, -lm)
#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.
None.
These function names are reserved for future use in C99.
Not yet in glibc, as at glibc 2.19.
