RE: TVM formula error in programming manual?
The sign convention for HP financial machines, for the associated cashflow diagrams to look 'right', is the Present value has the opposite sign of the Future Value (since one is paying, the other receiving) so the "-PV" may be negating the negative value you're supposed to use, if the underlying equations are assuming both positive. Not a math issue, just a sign convention issue.
