C# Complex32.Phase 怎么用转角度

//引入命名空间
using System;
using System.Numerics;

public class Example
{
   public static void Main()
   {
      Complex c1 = Complex.FromPolarCoordinates(10, 45 * Math.PI / 180);
      Console.WriteLine("{0}:", c1);
      Console.WriteLine("   Magnitude: {0}", Complex.Abs(c1));
      Console.WriteLine("   Phase:     {0} radians 弧度", c1.Phase);
      Console.WriteLine("   Phase      {0} degrees 角度", c1.Phase * 180/Math.PI);
      Console.WriteLine("   Atan(b/a): {0}", Math.Atan(c1.Imaginary/c1.Real));
   }
}

输出

(7.07106781186548, 7.07106781186547):
Magnitude: 10
Phase:     0.785398163397448 radians 弧度
Phase      45 degrees 角度
Atan(b/a): 0.785398163397448
