Question on complex arithmetic with 15c
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!

RE: Question on complex arithmetic with 15c
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.
