       this.member += val;

   }

   public void subtract(double val) {

       this.member -= val;

   }

   public void multiply(double val) {

       this.member *= val;

   }

   public void divide(double val) {

       this.member /= val;

   }

   public void clear() {

       this.member = 0.0;

   }
