|17Bii is Algebraic with Hierarchy? |
Message #1 Posted by Glen Kilpatrick on 17 Jan 2003, 1:19 p.m.
I'm reading about the "calculator line" under the subheading "Algebraic (With a Stack)", and puzzling over the lines:
For example if the user pressed 1+2*3, the calculator would show that expression in display. On pressing +6, the calculator would evaluate the part that it now could and display 7+6.
This suggests to me that 17Bii's do algebraic with hierarchy (1+2*3 -> 7, what I associate with scientific calcs) rather than algebraic without (1+2*3 -> 9, what I've heretofore seen on business calcs, _e.g._ on a 10B).
Might someone confirm that, and also advise about other HP Algebraic Business Calcs (are they with or without hierarchy)?
Some good tests might be:
1+2*3 ---> 7 (multiply over add, this is hierarchy)
1+2*3 ---> 9 (no hierarchy here)
1+2*3^4 ---> 163 (power over multiply over add, definitely algebraic hierarchy)
1+2*3^4 ---> 6,561 (you can guess this one)
