Complex.Zero 欄位

定義

命名空間:

System.Numerics

組件:

System.Runtime.Numerics.dll

來源:

Complex.cs

在實數等於零且虛數等於零條件下，傳回新 Complex 執行個體。

public: static initonly System::Numerics::Complex Zero;

public static readonly System.Numerics.Complex Zero;

 staticval mutable Zero : System.Numerics.Complex

Public Shared ReadOnly Zero As Complex 

欄位值

Complex

範例

下列範例會使用 Zero 屬性具Complex現化值。 然後，它會將這個值與另一個值進行比較，方法是呼叫 Complex 實數等於零且虛數部分等於零的建構函式來具現化。 如範例的輸出所示，這兩個值相等。

using System;
using System.Numerics;

public class Example
{
   public static void Main()
   {
      Complex value = Complex.Zero;
      Console.WriteLine(value.ToString());

      // Instantiate a complex number with real part 0 and imaginary part 1.
      Complex value1 = new Complex(0, 0);
      Console.WriteLine(value.Equals(value1));
   }
}
// The example displays the following output:
//       (0, 0)
//       True

open System.Numerics

let value = Complex.Zero
printfn $"{value}"

// Instantiate a complex number with real part 0 and imaginary part 1.
let value1 = Complex(0, 0)
printfn $"{value.Equals value1}"
// The example displays the following output:
//       (0, 0)
//       True

Imports System.Numerics

Module Example
   Public Sub Main()
      Dim value As Complex = Complex.Zero
      Console.WriteLine(value.ToString())
      
      ' Instantiate a complex number with real part 1 and imaginary part 0.
      Dim value1 As New Complex(0, 0)
      Console.WriteLine(value.Equals(value1))
   End Sub
End Module
' The example displays the following output:
'       (0, 0)
'       True

備註

屬性 Zero 最常用來比較 Complex 值與零。
