bool operator for Complex

using System;
public struct Complex
{
    public Complex( double real, double imaginary ) {
        this.real = real;
        this.imaginary = imaginary;
    }
    public override string ToString() {
        return String.Format( "({0}, {1})", real, imaginary );
    }
    public double Magnitude {
        get {
            return Math.Sqrt( Math.Pow(this.real, 2) + Math.Pow(this.imaginary, 2) );
        }
    }
    public static implicit operator bool( Complex c ) {
        return (c.real != 0) || (c.imaginary != 0);
    }
    private double real;
    private double imaginary;
}
public class MainClass
{
    static void Main() {
        Complex cpx1 = new Complex( 1.0, 3.0 );
        if( cpx1 ) {
            Console.WriteLine( "cpx1 is true" );
        } else {
            Console.WriteLine( "cpx1 is false" );
        }
        Complex cpx2 = new Complex( 0, 0 );
        Console.WriteLine( "cpx2 is {0}", cpx2 ? "true" : "false" );
    }
}

cpx1 is true
cpx2 is false
