Using newRPL on a 50g:
Entering A: 45 keystrokes
Entering B: 45 keystrokes
Computing X and Y: 14 keystrokes
Using newRPL on a Prime G1:
Computing X and Y: 10 keystrokes (because the x^2 key is not shifted and LN isn't shifted)
Total:
newRPL on Prime = 100 keystrokes
newRPL on 50g = 104 keystrokes
**EDIT**:
Starting with an empty stack, creating the lists for A and B can be done using the interactive stack in 6 and 7 keystrokes respectively (instead of 9+9), lowering the count to 95 for the Prime and 99 for the 50g.
Code:
Entering A:
5 ---- 3.12 [Ent] (enter 3.12 to the stack)
1 ---- [Ent] (second 3.12)
1 ---- [Ent] (third 3.12)
3 ---- [Ent] [Ent] [+] (6.24)
3 ---- [Ent] [Ent] [+] (12.48)
3 ---- [Ent] [Ent] [+] (24.96)
1 ---- [Ent] (second 24.96)
1 ---- [Ent] (third 24.96)
6 ---- 18.59 [Ent]
6 ---- 17.63 [Ent]
1 ---- [Ent] (second 17.63)
1 ---- [Ent] (third 17.63)
Total = 32 to enter the numbers
To make a list (12 ->LIST)
9 ---- 12 [Ent] [Shift][0] [Alpha]+[L]+[Right] [Ent]
To store as 'A' ('A' STO):
4 ---- [O] [Alpha]+[A] [M]
Total to enter A as a list and store it in variable 'A': 45
Entering B:
5 ---- 2.56 [Ent] (enter 2.56)
3 ---- [Ent] 2 / (enter 1.28)
3 ---- [Ent] 2 / (enter 0.64)
1 ---- [Ent] (second 0.64)
1 ---- [Ent] (third 0.64)
3 ---- [Ent] 2 / (enter 0.32)
3 ---- [Ent] 2 / (enter 0.16)
5 ---- 1.32 [Ent] (enter 1.32)
1 ---- [Ent] (second 1.32)
1 ---- [Ent] (third 1.32)
3 ---- [Ent] [Ent] + (enter 2.64)
3 ---- [Ent] [Ent] + (enter 5.28)
Total = 32 keystrokes to enter the numbers
+ 9 to make a list (same as case for A)
+ 4 to store it as 'B'
Total of 45 keystrokes to input B (by chance is the same as for A)
Computing X is 9 keystrokes (leaves X as a list on the stack, add 4 keystrokes if you want to store it on variable X but the benchmark did not specify that, only display):
[A] [A] [*] [A] [+] [B] [Shift] [LN] [-]
Finally, computing Y is 5 more:
[B] [B] [*] [Shift] [LN]
Total = 45 + 45 + 9 + 5 =104 keystrokes.
On a Prime G1 keyboard, though, computing X is only 7 keystrokes:
[A] [x^2] [A] [+] [B] [LN] [-]
and computing Y only 3:
[B] [x^2] [LN]
Hence the total = 45 + 45 + 7 + 3 =100 keystrokes.
PS: I think this is an interesting benchmark, should probably be moved to the general forum. I'd say if HP calculators are present in the benchmark, it's definitely HP calculator related.
