運算式的型態轉換

Code:

// ap6,運算式的型態轉換
 
public class ap6
{
   public static void main(String args[])
   {
      short s=-5;
      int i=6;
      float f=9.67f;
      double d=976e-2; //9.76
     
   System.out.print("(short*integer)=");
   System.out.println((s*i));
   System.out.print("(double/float)=");
   System.out.println((d/f));
   System.out.print("(integer+float)=");
   System.out.println((i+f));
   System.out.print("(double/float)*(integer+float)=");
   System.out.println((d/f)*(i+f));
   System.out.println(" ");         
      System.out.print("(s*i)-(d/f)*(i+f)=");  // 印出結果
      System.out.println((s*i)-(d/f)*(i+f));
      
      /*
      ((short*integer)->short)=-30
      ((double/float)->double)=1.00930712750734
      ((integer+float)->double)=15.67
      ((double/float)*(integer+float)->double)=15.81584276504404
      
      ((s*i)-(d/f)*(i+f)->short-double=double)=-45.81584276504404
      */
   }
}

Output:

(short*integer)=-30
(double/float)=1.00930712750734
(integer+float)=15.67
(double/float)*(integer+float)=15.81584276504404

(s*i)-(d/f)*(i+f)=-45.81584276504404
