 NPV# (rate#, valuearray#(), valuecount%, status%)
 
 Usage Notes
   ■ The differences between NPV# and PV# are:
 
         PV# cash flows                    NPV# cash flows
         ═══════════════════════════════   ═════════════════════════════════
         • Begin at the end or the start   • Occur at the end of the period
           of the period
         • Are constant throughout the     • Are variable
           investment
 
   ■ The argument rate# is the interest rate per period. For example, if you
     get a car loan at a 10% annual interest rate and make monthly payments,
     the rate per period would be .10/12, or .0083.
 
   ■ The argument valuearray#() must contain at least one negative value (a
     payment) and one positive value (a receipt).
 
   ■ The argument status% can be any variable that returns information about
     the success or failure of the calculation. The value of status% will be
     0 if the calculation was successful, and 1 if it was not.
 
   ■ The net present value of an investment is today's value of a future
     series of payments (negative values) and receipts (positive values).
 
   ■ The cash flow values must be equally spaced in time and occur at the
     end of each period.
 
   ■ NPV# uses the order of values within the array to interpret the order
     of cash flows. Be sure to enter your payment and receipt values in the
     correct sequence.
 
   ■ The NPV# investment begins one period before the date of the first cash
     flow value and ends with the last cash flow in the list.
 
   ■ The NPV# calculation is based on future cash flows. If your first cash
     flow occurs at the beginning of the first period, the first value must
     be added to the NPV# result, not included in the cash flow values of
     valuearray#().
