HP Prime G2 RPN use

[Vjsilva]

I am a G2 newbie and I have had the G2 only about a week so forgive me if this is a stupid question.
It is a very powerful calculator for graphing and solving, but sometimes I pick it up for a quick calculation, like an HP41 and it's different.

Does the G2 have a classic RPN interface?
I don't seem to be able to do something like:
1 ENTER 2 +

It appears like the G2 requires 1 + 2 ENTER, which is not RPN

Thanks,
Victor

Press [shift]>[home] to enter settings, then select the drop down menu next to 'Entry:' and select RPN.

I don't use RPN myself, but I've heard many times that RPN on the Prime is not nearly as good as HP's previous calculators.

I like both entry modes.
For math calculations, I find that Textbook mode is better because of readability and error fixing.
For every day quick calculations, I find RPN is the best.

Well, this means I have to go to the settings every time?

No, because of this program:

Code:


KEY K_Menu()
BEGIN
 local s:={"Textbook","Algebraic","RPN"};
 Entry := ABS(Entry-2);
 TEXTOUT_P(s(Entry+1), 15,9, 1, RGB(255,180,80));
 WAIT(1);
 RETURN −1;
END;

Usage: in User keyboard mode, press Menu.
Or simply: Shift Help Menu.
It toggles from RPN to Textbook, and vice versa.

Regards.

Prime has all the RPN functionality of old HP series calcuators, no problem there.. Its programming does not include RPN commands since it's a totally different architecture.

This is exactly what I was looking for, thanks!
