I can't think of any.

?

Just curious; when did they change that, even if it was after 1990?

I just see that on some current calculators, TI have changed from the old [y^x] button to a [X^□] button (which I think makes more sense on an algebraic calculator, if you think about the order of the arguments).


Here is a comparison between the current HP calc 35s and current TI calc 36X-Pro:

This looks very logic (to me at least) as 35s is RPN and 36X algebraic.


I think I have also seen just [^] on some current graphing TI calculators, and on some others TI's the classic algebraic version [x^y] (even if I do not remember which TI models).
