bool operator for Complex

<source lang="csharp">using System; public struct Complex {

   public Complex( double real, double imaginary ) {
       this.real = real;
       this.imaginary = imaginary;
   }
   public override string ToString() {

       return (c.real != 0) || (c.imaginary != 0);
   }

   private double imaginary;

} public class MainClass {

   static void Main() {
       Complex cpx1 = new Complex( 1.0, 3.0 );

           Console.WriteLine( "cpx1 is true" );

cpx1 is true
cpx2 is false
