HP49-50G Graduate TVM with/without PMT Growth & C/Yr =/≠ P/Yr + Amortization

[Gil]

New version 6

When requiring the evolution table with NB—>TABLE, the "amortisation" table will be adapted if PV is not a loan to be amortized, ie when PV is money initially brought/invested by the client, ie when PV is negative like PMT (or equal to zero), or more precisely when PV × PMT >= 0 (for instance, when deciding for payments PMT to be positive, instead of conventionally negative PMT, and then PV>=0).

For that special situation (not a loan, but an effective investment), when running NB—>TABLE, a column Int.End will be added after Int.Beg if the payments occur at period begin — just for control purposes ; besides, for investment case, the column "Principal" will be suppressed.

The results found here will of course match with the given cases suggested by Werner in his different posts. My thanks again to him for his various calculations and commentaries.
