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.
