Well, how about this:

/* BEGIN */
#include <stdio.h>

#define Round(i,f) i=(int)f;\
                   if ((double)i+0.5<=f) i++

main()
{ int i;
  double f;

  f=123.456;
  printf("Floating value: %f\n",f);
  Round(i,f);
  printf("Floating value rounded to an integer: %d\n",i);

  f=234.567;
  printf("Floating value: %f\n",f);
  Round(i,f);
  printf("Floating value rounded to an integer: %d\n",i);
};
/* END */

I belive that's what you are looking for!?
I myself have just invented this to be used with a graphics-program of mine!
It's on purpose I made it look like a function! Because performance is
crucial, it has been put into a #define, but of course - it could be a
function if you'd like!
