Hi, C.Ret,

Of course there is ! Matter of fact you need no program to do it, that's just Mr. Weber doing his thing ...

From the keyboard, do this to enter 1+2i, 3+4i, 5+6i and 7+8i into the RPN stack:

1, ENTER, 2, COMPLEX, STO A {... or any other variable}
3, ENTER, 4, COMPLEX,
5, ENTER, 6, COMPLEX,
7, ENTER, 8, COMPLEX, RCL A, Rdown

... and there you are, simple and effortless.
