It's about TVM and Cashflow calculations, and it has a lot of possible settings  you can find it on my website (and it's free!): http://fhub.jimdo.com/ Franz

Danke, thank you. Very useful also your program. I've downloaded and used it just now. Salvo ∫aL√0mic (IT9CLU) :: HP Prime 50g 41CX 71b 42s 39s 35s 12C 15C  DM42, DM41X  WP34s Prime Soft. Lib

RE: A formula for IRR
hi,
you can find in the HP Prime Software Library a much better version of the program, or ...two version: the first with the single functions exported (the user can recall them separately), the second with Drawmenu (every functions inside, but with a graphic interface). I had to use a trick to avoid a strange erratic first argument output by solve() with the function for IRR, with a IRR value greater than 1 (100%) in some cases but not all... Code:
please, control with examples, if possibles... Enjoy! Salvo ∫aL√0mic (IT9CLU) :: HP Prime 50g 41CX 71b 42s 39s 35s 12C 15C  DM42, DM41X  WP34s Prime Soft. Lib
