(10C) Financial Program

[Gamo]

HP-10C financial program.

From PPC Calculator Journal V10N8 October 1983 Page 39

As state in this journal somehow the routine provide is not woking as expected.

The n, i, PV, PMT, FV store register are in wrong order so the routine is not work.

I have updated this program provided with actual interest in percent no need to

enter interest in decimal value.

----------------------------------------------

Procedure:

Key in as follows:
[n] STO 1
[i] STO 2
[PV] STO 3
[FV] STO 5

FOR [GIVEN] KEY
i [n, PV, FV] PRGM, R/S
PMT [n, i, PV] GTO 60, R/S, R/S // each problem can be repeat no need to re-enter GTO 60
PV [n, i, FV] GTO 61, R/S, R/S // simply input new data and press R/S
FV [n, i, PV] GTO 62, R/S, R/S

Remark:
For easy to remember begining of the program PRGM or GTO 00 is

to solve for i problem, GTO 60 to solve for PMT, GTO 61 to solve for PV and

GTO 62 to solve for FV each time user go to each problem the same problem

can be run again in a loop until change to different problem.
