// Integer and floating-point division 

 int main(){
   ... 

»  int j=5, k=3;
»  double x, y;

// Do division as integers:
»  x=(j+7)/(k*6-j*4+12);

// Do division as floating-point: 
// Converting one int to floating-point is enough
»  y=(j+7.0)/(k*6-j*4+12);

// But converting them all is safer
»  y=(j+7.0)/(k*6.0-j*4.0+12.0);

»  printf("x: %g y: %g\n", x, y);

»  return 0;
