In this example, your input of complex numbers is processed by this small Ch CGI script with less than 60 lines of code. The imaginary part of a complex number, such as 2+i3, can be represented either in 2+I*3 or complex(2,3).

You can download Ch Standard Edition and Ch CGI toolkit to run this demo in your Web server.
