This is a solver for problems involving the time value of money (TVM). It emulates the TVM solver on the TI-83+ and TI-84 graphing calculators.[br][br]The seven TVM variables are as follows.[br]N The number of payments[br]I% The interest rate, as a percentage. It should not be divided by 100.[br]PV Present value[br]PMT Periodic payment[br]FV Future value[br]P/Y Payments per year[br]C/Y Times per year that interest is compounded[br][br]You must press Enter or Tab after entering a value in the input box, or the value will not be updated. Note that inflows of cash are considered positive and outflows are negative.[br][br]This is a preliminary version, and it may have bugs. In particular, solving for I% may give incorrect values if the inputs are extreme.[br][br]Tutorial: http://analemma.wikispaces.com/file/view/TimeValueOfMoneyTI-83Plus.pdf
