(11C) Compound Calculations - Gamo - 04-10-2018 12:21 PM
This program calculate compound solutions. Provide any three out of four variables for the result of the remaining variable for [n] [i] [PV] [FV] LBL A for [n] period LBL B for [i] interest LBL C to Reset LBL D for [PV] Present Value LBL E for [FV] Future Value Remark: Each input data indicate as 0.00 on display with FIX 2 This program didn't use sign convention where money paid out is negative. Example: switch to USER mode f USER 10 > A > 0.00 (Store [n]) 10 > B > 0.00 (Store [i]) 1000 > C > 0.00 (Store [PV]) remaining variable is [FV] E > 2593.74 is the answer for [FV] If [i] change to 7 what is the [FV] 7 > B > 0.00 (Store new [i]) E > 1967.15 (answer for new [FV] when [i] is 7%) To start a new problem: LBL C to Reset Program: Code:

But you should remove this line from the example: (04-10-2018 12:21 PM)Gamo Wrote: Answer of [FV] 2593.74 on display > input to [FV] > E > 0.00 Unlike the previous pricing program, this one does store a calculated result in the respective register. So you do not have to re-enter it if you want to continue with this value. In this example a new input isn't required even if the result had not been stored. You just have calculated FV, and now you change the interest rate to calculate a new FV. So the old one is overwritten anyway. You do not need the old FV to calculate a new one. ;-) (04-10-2018 12:21 PM)Gamo Wrote: Program: The code looks very good. However, if possible, I would avoid clearing all registers. This way the user loses all data he may have stored. So it's always a good idea to clear only the required registers. At least on a calculator with constant memory.

Thank You Dieter Updated the instruction and program. Gamo |
