This class defines a complex number and can perform operations on it, such as mulitplication and addition.

CComplexNumber.as Sample:

package ComplexNumber
{
	public class CComplexNumber
	{
		public var _real:Number;
		public var _img:Number;
		
		public function CComplexNumber(real:Number=0,img:Number=0)
		{
			_real = real;
			_img = img;
		}
		
		public function r() : Number
		{
			return _real;
		}
		
		public function i() : Number
		{
			return _img;
		}
		
		public function multc(n1:CComplexNumber,n2:CComplexNumber) : CComplexNumber
		{
			var n3:CComplexNumber = new CComplexNumber(0,0);
			
			n3._real = n1._real*n2._real - n1._img*n2._img;
			n3._img = n2._real*n1._img + n1._real*n2._img;
			return n3;
		}
		
		public function divn(c:CComplexNumber,n:Number) : void
		{
			c._img /= n;
			c._real /= n;			 
		}
		
		 public function subc(n1:CComplexNumber,n2:CComplexNumber) : CComplexNumber
		{

		{
