(41) Profit on Pricing Solver - Gamo - 12-29-2019 05:51 AM Profit on Pricing is based on four data. 1. Cost 2. Selling Price 3. Markup 4. Margin User provide two known data and program will find the two remaining unknown. The only exception is that the two known data cannot be Markup with Margin. But Markup and Margin can be calculate by itself between it. Assign each Cost, Price, Markup and Margin to the top row keys from left to right. To assing key: f [ASN] COST [A] // Sigma + key f [ASN] PRICE [B] // 1/x key f [ASN] Markup [C] // Square Root key f [ASN] Margin [D] // LOG key f [ASN] RESET [E] // LN key Example: [USER] [FIX] 2 Cost 88 and Margin 20 what is Price and Markup? [E] display 0.00 // This use for clearing register 1 to 4 and Initialize. 88 [A] display 88.00 // Press and hold not more than 1 second will show COST monentary on display 20 [D] display 20.00 // Press and hold on other remaining keys will show Name of that Labels. [B] display 110.00 // Price [C] display 25.00 // Markup Remark: Example above user can go to [C] then [B] as well. [A] [D] to [B] [C] or [C] [B] Program: Quote:01 LBL COST Gamo 12/29/2019 RE: (41) Profit on Pricing Solver - David Hayden - 12-29-2019 03:21 PM You could save some space and avoid having to assign to programs to keys by using labels A-E instead of the COST, PRICE, MARGIN, MARKUP and RESET. Also, should RESET clear flag 00? That would only be necessary if a path assumes it's clear rather than clearing it explicitly. Thanks for posting. I saw your 65 version on facebook and tried writing my own version. It's at least 25% longer than yours ![]() Dave RE: (41) Profit on Pricing Solver - Gamo - 12-30-2019 03:37 AM Thank You Dave Thanks for the review. The algorithm use is by attemping to find the Markup. The key to all the answer is first to get the answer for Markup. If the unknown is Markup then the special formula is use to convert Margin to Markup and if the Markup is known this same special fourmula will get the Margin as well. The flags is very important in this type of problem since user can enter data in many combination pair of data and still get the answer. The flowchart is available in the HP-12C link provided below. I intended to use alpha labels because when press and hold the key for less than a second display will show that label name effect. The flags used in program seem to work anytime even though the new problem is enter without clearing flags. The RESET option is only use for clearing the data registers. The reason that I write this program because HP-12C doesn’t include this function where most Financial Calculator have it. I also write this program for 12C too, but to enter data user must fill the four data in stacks and run. The answer will be in the TVM labels. To see the answer simply recall TVM label. https://www.hpmuseum.org/forum/thread-13043.html My first HP calculator is the HP 10BII and it got this Pricing Calculation feature. This program work better than the 10BII because it can calculate between Markup and Margin by itself. I’m very thankful to Dieter who help make this program possible. Gamo RE: (41) Profit on Pricing Solver - Gamo - 05-12-2020 04:45 AM Updated Profit on Pricing Solver now adapted to work on Free42 the HP-42S Simulator App. This update program came with the Soft Menu on display with Beep and Tone on each of the key press depending on different combinations of keys press sequences the audible sound out different tone for interactive purpose and kind of more fun to use....maybe. Video Clip link: https://youtu.be/edcJrEYXR7g Remark: The program listing is in the description and user need to add the Soft Menu individually. For the audible sound recommend to use Tone 0 to 5 on each of the Label 00 to 05 and use Beep sound on each of the program ending for smoother sound melody. This Profit on Pricing program can also be use as a [TAX+] and [TAX-] by using only Three keys on [COST] [PRICE] and [MARKUP] To calculate for an item including tax input item amount to [COST] and Tax% to [MARKUP] and answer out to [PRICE] To calculate for an item without tax input item amount to [PRICE] if same tax as above go ahead to got answer out to [COST] Gamo 5/12/2020 |
