-----------
7.3.9.2 The cimag functions
Sysnopsis
#include <complex.h>
double cimag(double complex z);
float cimagf(float complex z);
long double cimagl(long double complex z);
-----------
Well the truth is elsewhere ;-)
I have seen this paragraph, but it is a smoke screen, as there are also
creal and cimag *macros* mentioned in C99 that are described as applicable
to all three complex types and extract the corresponding part without
intermediary or final conversion (!)
C99 has created such a mine field around complex numbers and floating point
in general...
