          public Stack()         { storage = new double[100];  top = 0; }
          public Stack(int size) { storage = new double[size]; top = 0; }
          public void clear()    { top = 0; }
          public void push( double dbl) { storage[top++] = dbl; }
          public double pop()    { return storage[--top]; }
          public boolean full()  { return top == storage.length; }
          public boolean empty() { return ( top == 0 ); }
  
          // Data members:
          private double storage[ ];
          private int top;
