BigInteger.Subtract(BigInteger, BigInteger) メソッド

定義

ある BigInteger 値を別の値から減算し、その結果を返します。Subtracts one BigInteger value from another and returns the result.

``````public:
static System::Numerics::BigInteger Subtract(System::Numerics::BigInteger left, System::Numerics::BigInteger right);``````
``public static System.Numerics.BigInteger Subtract (System.Numerics.BigInteger left, System.Numerics.BigInteger right);``
``static member Subtract : System.Numerics.BigInteger * System.Numerics.BigInteger -> System.Numerics.BigInteger``
``Public Shared Function Subtract (left As BigInteger, right As BigInteger) As BigInteger``

left
BigInteger

right
BigInteger

戻り値

BigInteger

`right` から `left` を減算した結果。The result of subtracting `right` from `left`.

注釈

カスタム演算子をサポートしない言語では、 Subtract メソッドを使用して BigInteger 値を使用して減算を実行できます。Languages that do not support custom operators can use the Subtract method to perform subtraction using BigInteger values.

Subtractメソッドは、 BigInteger 次の例に示すように、減算の結果と異なる値を代入することによって変数をインスタンス化する場合に、減算演算子に便利な代替です。The Subtract method is a useful substitute for the subtraction operator when instantiating a BigInteger variable by assigning it the difference that results from subtraction, as shown in the following example.

``````// The statement
//    BigInteger number = Int64.MinValue - Int64.MaxValue;
// produces compiler error CS0220: The operation overflows at compile time in checked mode.
// The alternative:
BigInteger number = BigInteger.Subtract(Int64.MinValue, Int64.MaxValue);
``````
``````' The statement
'    Dim number As BigInteger = Int64.MinValue - Int64.MaxValue
' produces compiler error BC30439: Constant expression not representable in type 'Long'.
' The alternative:
Dim number As BigInteger = BigInteger.Subtract(Int64.MinValue, Int64.MaxValue)
``````
