示例

下面的示例演示了如何使用 Subtract。

   public ref class PiggyBank
   {
   public:
      Decimal Cents()
      {
         return Decimal::Subtract( MyFortune, Decimal::Floor( MyFortune ) );
      }

      void AddPenny()
      {
         MyFortune = Decimal::Add(MyFortune, (Decimal).01);
      }

   protected:
      Decimal MyFortune;
   };
}

class PiggyBank {
    public decimal Cents {
        get {
            return Decimal.Subtract(MyFortune, Decimal.Floor(MyFortune));
        }
    }

    protected decimal MyFortune;

    public void AddPenny() {
        MyFortune += .01m;
    }
}

type PiggyBank() =
    let mutable myFortune = 0m

    member _.Cents =
        Decimal.Subtract(myFortune, Decimal.Floor myFortune)

    member _.AddPenny() =
        myFortune <- myFortune + 0.01m

Class PiggyBank
    Public ReadOnly Property Cents() As Decimal
        Get
            Return [Decimal].Subtract(MyFortune, [Decimal].Floor(MyFortune))
        End Get
