Operational confusion?

New comment

I cant see why the object "margin" is returning 0.0 and not 0.5 like it should? 

void OnTick()
{
   double margin = (5 / 10);

   Print("margin = ",margin);
}

Have a read here to find out why:

   int    i=1/2;        // no types casting, the result is 0 
   Print("i = 1/2  ",i); 
  
   int k=1/2.0;         // the expression is cast to the double type, 
   Print("k = 1/2  ",k);  // then is to the target type of int, the result is 0 
  
   double d=1.0/2.0;    // no types casting, the result is 0.5 
   Print("d = 1/2.0; ",d); 
  
   double e=1/2.0;      // the expression is cast to the double type, 
   Print("e = 1/2.0; ",e);// that is the same as the target type, the result is 0.5 
  
   double x=1/2;        // the expression of the int type is cast to the double target typr, 
   Print("x = 1/2; ",x);  // the result is 0.0
