RE: Casio FC200 Financial Consultant
I've got a couple of programs I use on mine. For readability, I've replaced the colons between statements with newlines. Use colons to separate statements when entering these.
Weekdays Calculates weekdays/working days within a date range. Use the DATE key for inputting the two dates, e.g. 12/21/2020/ (yes, you need that final slash). Date A should be the earlier date. Code: ?→A Paydown/curtailment savings Estimates the amount of interest saved over the remaining life of a loan if an extra principle payment of a given size is made. The financial variables should already contain the current parameters of the loan such that FV=0. Financial variables are written in lowercase. Use RCL to insert them into formulas. Code: ?→A

RE: Casio FC200 Financial Consultant
Hello Dave

(12242020 06:02 AM)Gamo Wrote: Hello Dave Well that's interesting! At a glance, I can't figure out why it would do that. The program first calculates the actual number of days between the two dates, then calculates the number of days mod 7 since 1/6/1901 to work out the starting weekday. Must be some edge case I missed, as I don't think this has anything to do with February having fewer days. This was based on a 12C program I wrote; I'll have to see if that one has the same issue.

RE: Casio FC200 Financial Consultant
I just ran a few test cases for dates in/around February, and I seem to be getting correct results (2/1/20212/28/2021 is 20, for example). I've doublechecked that the program listing is accurate, so you may want to take a look for any typos in your entry. The last few lines that check W and W+M adjust for ranges that start/end on weekends, so you might want to look there first.

RE: Casio FC200 Financial Consultant
Thanks Dave
Just figured out what cause the wrong answer. I didn't noticed that the calculator Date was set to 360 days mode. Once I set to 365 the answer is now correct. Gamo

RE: Casio FC200 Financial Consultant
We can make the code more compact, with sign function.
PHP Code: function sign(x) return x==0 and 0 or x/abs(x) end Update: the code had a bug, when A falls on Sunday. Shifting it to Monday fixed it, matched openoffice networkdays() results.

Maybe it's works on 3650P and similar models. I have checked on my 4000P (seems same as FC models) this causes Syntax error. Csaba

Yeah, I don't think Casio changed the relational/comparison operators to work like actual mathematical functions until somewhere around the fx9750G/cfx9850G. Prior to that, you could only use them in conjunction with the 'if/then' arrow.

RE: Casio FC200 Financial Consultant
Here is an implementation without sign(), and very fast.
Code: function networkdays(A, B)  assumed date A <= B Sunday to Saturday is the tricky one, where my previous attempts failed. FYI, Dave's posted code might failed this too. Please confirm. lua> networkdays(day(2021,2,28), day(2021,3,5))  Sun to Fri 5 lua> networkdays(day(2021,2,28), day(2021,3,6))  Sun to Sat 5 lua> networkdays(day(2021,2,28), day(2021,3,7))  Sun to Sun 5

RE: Casio FC200 Financial Consultant
Just play around a bit more on this Casio FC200 Financial Consultant calculator.
So I make a small and very handy program to use for total up a group of items price with different discount percentage rate on each group. This program use the Statistic Funtions to help in accumulate each items.  Discount Percent and Total 1. Following items is 15% discount 12.45, 55.75, 18.50, 10.25 and 75.75 Total = 172.70 Total  (15%) = 146.80 Grand Total = 146.80  2. Following items is 20% discount 127.15, 215, 115 and 215.65 Total = 672.80 Total  (20%) = 538.24 Grand Total = 146.80 + 538.24 = 658.04  Procedure: Fix 2 Setup: 0→M Mode 6  Input each items to [DT] the **[MAR] button** Select [Prog] # where you put this program ?D input Discount Percent Rate [EXE] Items Total [EXE] Total subtract Discount [EXE] Grand Total To input next group of items [Prog] # and same steps as above.  Program: ?→D: T◢ Ans  D%: Scl◢ Ans + M →M  Remark: The Apha Letter T in program is the [Σx] function and this function does not show Summation on the screen in program but Shown as Letter T instead. To put [Σx] in program enter [ALPHA] [2] and screen shown letter T Program must activate the Statistic Mode 6 [SD] and program will automatically clear Satistic Data on each usage so that new group of data is always ready.

RE: Casio FC200 Financial Consultant
This calculator got the Pricing Calculations to find Cost, Price or Margin but no Markup.
This program will will find the Markup when the Margin is known. Even if only the Markup is known another program will find the Margin and automatically store it. Program #8 for convert Markup and store into the Margin Program #9 for Convert Margin to Markup  Example: Cost = 8 and Markup = 25 what is the Price? 25 [MAR] [Prog] 8 [EXE] display 20 8 [CST] [COMP] [SEL] [EXE] display answer 10 Answer: Price is 10  Cost = 15 and Price = 28 what is the Markup? 15 [CST] 28 [SEL] [COMP] [MAR] display 46.43 [PROG] 9 [EXE] display answer 86.67 Answer: Markup is 86.67  Program: Program P8 MAR^1 + .01: Ans^1: Ans→MAR Program P9 MAR^1  .01: Ans^1  Remark: The MAR at the start of each program when enter use [RCL] [MAR] The ^1 is the (1/x) this model use [X^1] the key located at the [SHIFT] [STO]  Gamo 5/2021

RE: Casio FC200 Financial Consultant
Program P8 on previous post can be use as the [Tax ] or Tax Exclusive
[Tax ] is when price is already included tax or VAT and this function is to find the price not include tax or VAT. For Example: This product you pay already included tax is 550 The Tax Rate is 20% What is the price not include tax? 20 [MAR] [Prog] 8 [EXE] display 16.67 // set up the Tax Rate 550 [SEL] [COMP] [CST] [EXE] display 458.33 // Answer Price without Tax or VAT To find the Tax Amount: [RCL] [SEL]  [RCL] [CST] [EXE] display 91.67  You go to other place and got another product for 80 What is the price without tax or VAT? While the Tax Rate data still in the memory go ahead and continue 80 [SEL] [COMP] [CST] 66.67 To find Tax Amount: [RCL] [SEL] [] [RCL] [CST] [EXE] display 13.33 Remark: This Pricing Calculation program can adapted to use for [Tax] and [Tax+] The "Tax Rate" have to convert and store to [MAR] by the use of the P8 program. Use [CST] for [Tax] USE [SEL] for [Tax+] Example: To find Price with Tax: Price [CST] [COMP] [SEL] [EXE] To find Price without Tax: Price [SEL] [COMP] [CST] [EXE] Gamo

RE: Casio FC200 Financial Consultant
This program use for conversion between Markup and Margin since
calculator only have [CST] [SEL] and [MAR] it doesn't have Markup. First section of this program convert Markup to Margin and Store result to [MAR] Second section covert Margin to Markup. Example Usage: Program Store to P0  The Selling Price is $2354 and Markup is 7% What is the Cost? [Prog] 0 [EXE] display U? 7 [EXE] display 6.54 [AC] 2354 [SEL] [COMP] [CST] [EXE] display answer: 2'200.00  Previous Data from last problem is still intact if Cost is 1100 What is the Selling Price? 1100 [CST] [COMP] [SEL] [EXE] display answer: 1'177.00  Convert Margin to Markup: Margin is 20% What is the Markup? [Prog] 0 [EXE] display U? // Enter any number except 0 this case I put 1 1 [EXE] display 0.99 ignore this result and press [EXE] display M? 20 [EXE] display answer: 25.00  Program: ?→U: (U1+.01)1→MAR◢?→M: (M1.01)1◢ Remark: U1 and M1 and (xxx)1 is located at [STO] key indicated as X^1 This code shown as →MAR simply press [MAR] Gamo 3/2022
