Question on complex arithmetic with 15c

[lemontea]

Hi all,

I read this post

http://www.hpmuseum.org/cgi-sys/cgiwrap/...ead=137175

but don't understand it! :-)

If I type in that program, can someone explain how do I use it for calculating with complex numbers?

(I am calculating electrical impedance so just need to work in two dimensions with the "a + jb" format; I do have a complex number RPN app on my iPhone but it would be handier to grab my 15c on the table and do it).

Thanks!
