五个最常用的财务金融计算公式 ( FV

This module is freeware and can be used without restriction.

This is my small contribution back to the community of Delphi developers who
have helped me by their contributions.

This module contains five of the most frequently used financial
calculations used.  These calculations are:

        1.      FV (Future Value).  Use this calculation to determine
                how a fixed sum invested at a given interest rate for
                a given period of time will grow.
        2.      PV (Present Value).  Use this calculation to determine
                how much a future sum of money is worth in terms of
                todays value.
        3.      PVa (Present Value Annuity).  Determine what a future
                fixed sum of money must be in order to receive a monthly
                payment.
        4.      FVa (Future Value Annuity).  Determine the future value
                of a series of payments.
        5.      PMT (Payment).  Determine what the payment is of a given
                principal.

This module also contains a generalized exponent function -- something
that is lacking in Object Pascal.

Notes On Use:

        A.      Interest rate is the annual interest rate.  For example,
                assuming 12% valid entries would be 12 or .12
        B.      Monthly compounding is assumed
        C.      All annuity calculations are 'end' mode.
        D.      Term or Period is always expressed in terms of the total
                compounding periods (12 per year * number of years).
                Therefore a five-year term would be expressed as 60 (5 * 12)
        E.      You must validate values before passing them to the
                modules -- there is no error handling in the calculations.

Installation:

        i.      Open the Demo project 'CalcDemo' to see how routines
                work and how they are called
        ii.     To include these routines in your application, load the
                FINCALC.PAS file into your project and place a reference
                to FINCALC in the 'uses' section of the form from which
                you call these routines.

Warranty:

        None.  These routines are offered 'as is' with no warranty
        whatsoever.  Use at your own risk and descretion.
