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!
The 15c handles complex numbers pretty well. Unless you need the fuctions added by that program, you don't need it.
Just set flag 8 and all built in functions are now complex. You can edit real and imaginary part using the re <> im button. The 15c manual is availaböe online from hp an describes all this in detail.
OK thanks. Now that you mention it, it rings a little bell.

Will check the manual.

Pls post the example here!
Thnx!
