# BigInteger.Compare(BigInteger, BigInteger) メソッド

## 定義

2 つの BigInteger 値を比較し、1 番目の値が 2 番目の値よりも小さいか、同じか、または大きいかを示す整数を返します。

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

left
BigInteger

right
BigInteger

#### 戻り値

Int32

`left``right` の相対値を示す符号付き整数。次の表を参照してください。

[値] 条件
0 より小さい値`left``right` より小さい値です。
ゼロ`left``right` は等しい。
0 より大きい値`left``right` より大きくなっています。

## 注釈

``````BigInteger number1 = BigInteger.Pow(Int64.MaxValue, 100);
BigInteger number2 = number1 + 1;
string relation = "";
switch (BigInteger.Compare(number1, number2))
{
case -1:
relation = "<";
break;
case 0:
relation = "=";
break;
case 1:
relation = ">";
break;
}
Console.WriteLine("{0} {1} {2}", number1, relation, number2);
// The example displays the following output:
