Thanks for the tip. Just curious,

With the real number range, 3^5 would be entered as 3 ENTER 5 y^x. So why would complex numbers need to be entered in reverse (3+5i as 5 [5 ENTER 3 ENTER])?

To be clear: to work out (1+2i)^(3+4i) you would enter (on the RPN-67 and similar machines):

2 ENTER 1 ENTER 4 ENTER 3 y^x.

At least, I think so. Try it and see!
