BigInteger

除算の結果 (整数)。

実装

Division(TSelf, TOther)

例外

DivideByZeroException

divisor が 0 (ゼロ) です。

例

次の例では、値の配列を BigInteger 作成します。次に、メソッド、除算演算子 (/)、およびメソッドを Divide 使用する除算操作で、各要素を DivRem 商として使用します。

注釈

メソッドは Division 、値の除算操作を BigInteger 定義します。これにより、次のようなコードが有効になります。

BigInteger num1 = 100045632194;
BigInteger num2 = 90329434;
BigInteger quotient = num1 / num2;

let num1 = 100045632194I
let num2 = 90329434I
let quotient = num1 / num2

Dim num1 As BigInteger = 100045632194
Dim num2 As BigInteger = 90329434
Dim quotient As BigInteger = num1 / num2

カスタム演算子と演算子のオーバーロードをサポートしていない言語では、代わりにメソッドを Divide 呼び出すことができます。

この演算子の同等のメソッドは次のようになります。 BigInteger.Divide(BigInteger, BigInteger)
