Each of these macros expands to an expression that evaluates to the value of the specified complex type, with the real part having the value ofreal (converted to the specified argument type) and the imaginary part having the value ofimag (converted to the specified argument type)

The expressions are suitable for use as initializers for objects with static or thread storage duration, as long as the expressionsreal andimag are also suitable.

[edit]Parameters

[edit]Return value

A complex number composed ofreal andimag as the real and imaginary parts.

[edit]Notes

These macros are implemented as if the imaginary types are supported (even if they are otherwise not supported and_Imaginary_I is actually undefined) and as if defined as follows:

#define CMPLX(x, y) ((double complex)((double)(x) + _Imaginary_I * (double)(y)))#define CMPLXF(x, y) ((float complex)((float)(x) + _Imaginary_I * (float)(y)))#define CMPLXL(x, y) ((long double complex)((long double)(x) + \                      _Imaginary_I * (long double)(y)))

[edit]Example

#include <stdio.h>#include <complex.h> int main(void){doublecomplex z= CMPLX(0.0,-0.0);printf("z = %.1f%+.1fi\n",creal(z),cimag(z));}

z = 0.0-0.0i
