Complex(Double, Double) 建構函式

定義

使用指定的實數和虛數,初始化 Complex 結構的新執行個體。

C#
public Complex(double real, double imaginary);

參數

real
Double

複數的實數部分。

imaginary
Double

複數的虛數部分。

範例

下列範例會具現化兩個複數,然後另外使用複數、減法、乘法和除法運算。

C#
using System;
using System.Numerics;

public class Example
{
   public static void Main()
   {
      Complex complex1 = new Complex(17.34, 12.87);
      Complex complex2 = new Complex(8.76, 5.19);

      Console.WriteLine("{0} + {1} = {2}", complex1, complex2,
                                          complex1 + complex2);
      Console.WriteLine("{0} - {1} = {2}", complex1, complex2,
                                          complex1 - complex2);
      Console.WriteLine("{0} * {1} = {2}", complex1, complex2,
                                          complex1 * complex2);
      Console.WriteLine("{0} / {1} = {2}", complex1, complex2,
                                          complex1 / complex2);
   }
}
// The example displays the following output:
//    (17.34, 12.87) + (8.76, 5.19) = (26.1, 18.06)
//    (17.34, 12.87) - (8.76, 5.19) = (8.58, 7.68)
//    (17.34, 12.87) * (8.76, 5.19) = (85.1031, 202.7358)
//    (17.34, 12.87) / (8.76, 5.19) = (2.10944241403558, 0.219405693054265)

備註

real如果 或 自變數是需要明確轉換成 Double的數據類型,這些自imaginary變數可能會失去精確度。
