This, I have not found on the "newer" calcs, and so also not on this one. I can of course set it to polar and just insert the rectangular calculation and receive the polar answer. But, as is a main concern here at hpmuseum regarding this inconvenience on the HP 35S, noone seems to think it is an inconvenience on this one..?
Or - did I miss something?

Press OPTN, and open the ANGLE menu. You'll find Pol( and Rec( for this purpose. Give them two arguments, and they return a list with two elements, e.g. Pol(5,2). You can either store the result of the function directly in a list of your choosing, or simply call the function and access the results in List Ans.
