HP 10BII Percentage of Total

[Gamo]

Since HP 10BII and 10BII+ doesn't have the Percentage of Toatal feature

like on the HP-12C

These steps will solve "Percentage of Total" by the use of the

[K] and [→M] memory functions.

-----------------------------------------
Example Usage with FIX 2 ( [DISP] 2 )

Data: 13, 9, 6 and 15

Steps:

13 [→M] 9 [M+] 6 [M+] 15 [M+] // Accumulate Total



13 [÷] [RM] [K] [=] 0.30 // Recall Memory and use constant memory calculation

9 [=] 0.21

6 [=] 0.14

15 [=] 0.35

Answer:
13 to 0.30 is 30%
9 to 0.21 is 21%
6 to 0.14 is 14%
15 to 0.35 is 35%

To check answer all percent should add up to 100
30 + 21 + 14 + 35 = 100

Nihotte(lma) Thank You

This calculator can also be use just like the [Tax-] and [Tax+] too.

The steps is here:

HP 10B to 10BII+ doesn't show the way on how to

calculate the "Moving Average" as demostrated on the

HP-12C Platinum "Soultions Handbook" on page 74

I'll use the same Example as shown in this Solutions Handbook.

Steps: [DISP] 2

[CLΣ] [C ALL]

211570 [STO] 1 [Σ+] display 1.00 // Use Store Registers for easy retrieval
112550 [STO] 2 [Σ+] display 2.00
190060 [STO] 3 [Σ+] display 3.00

[ x̅ ] display answer 171,393.33 // X bar is on the [7] key

[RCL] 1 [Σ-]
131760 [Σ+] [ x̅ ] display answer 144,790.00

[RCL] 2 [Σ-]
300500 [Σ+] [ x̅ ] display answer 207,440.00

[RCL] 3 [Σ-]
271120 [Σ+] [ x̅ ] display answer 234,460.00
