help about CalcPV, CalFV - Printable Version +- HP Forums (https://www.hpmuseum.org/forum) +-- Forum: HP Calculators (and very old HP Computers) (/forum-3.html) +--- Forum: HP Prime (/forum-5.html) +--- Thread: help about CalcPV, CalFV (/thread-3924.html) help about CalcPV, CalFV - salvomic - 05-20-2015 06:12 PM hi, I need some info about Finance.CalcPV and Finance.CalcFV The help is: Finance.CalcPV(NbPmt, IPYR, PMT, FV [PPYR, CPYR, BEG]) Finace.CalcFV(NbPmt, IPYR, PV, PMT [PPYR, CPYR, BEG]) is it intended the inversion between "PMT, FV" and "PV, PMT"? for symmetry, maybe, use the same series would be better... However, the help says BEG is 0 for "end" and 1 for "begin"... I input (in command line) Finance.CalcPV(48, 5.9, -450, 0, 12, 12, 0) and I get PV=19292.993 with Finance.CalcPV(48, 5.9, -450, 0, 12, 12, 1) I get PV=19198.6 With my 12C 19198.6 is the result for "END" period, not for "BEGIN", and the other is for BEGIN (and not END). Also with the Finance App I get the result (correctly) inverted... In the Prime command line is there another logic? the help is wrong? or... idem about Help for Beginning in CalcFV... BEG=0 is end and BEG=1 is begin? or Am I confused? is the default value 1 or 0? In HELP I read "BEG: payments made at the beginning(1) or end(0) of the period"... Salvo
