10.4: Be aware of a Calculator widget bug
Intuitive? Huh? I'll agree that it's non-ambiguous, but intuitive, no. When I see 1+2*3, I think "One plus two times three", and that's how I expect to punch it in. I do not think "One Two Three Plus Times", so RPN is not intuitive; non-ambiguous, sure, but not intuitive.

It's not necessarily unintuitive, it's just different from what we're taught in school. I learned RPN when I got an HP 48-GX for college, and I've never looked back. The appeal of RPN entry is that it's simpler and, as you said, not ambiguous. You first provide the data you're working with and then specify what you want done with that data. It comes down to personal preference; I think it's easier to work in RPN.

Actually, in RPN, if you wanted to do 1+2*3 you would do 1 2 3 * +.

Actually, it's 19 vs 19 keystrokes, not 14 vs 28. For the RPN you forgot to count the ENTERs between values (otherwise 2 8 is 28), and for non-RPN there were too many parenthesis as you said (and the last one can be dropped because = closes it automatically). |
