All Implemented Interfaces:

final class IFTables

extends java.lang.Object

implements java.io.Serializable

Interest Factor Tables
This class simulates interest factor tables which contain the present or future values for single units of currency:

• Future Value of 1: FVIF_n,i = (1 + i)ⁿ
• Present Value of 1: PVIF_n,i = 1 / (1 + i)ⁿ
• FV of an Annuity of 1: FVAIF_n,i = [(1 + i)ⁿ - 1] / i
• PV of an Annuity of 1: PVAIF_n,i = [1 - 1 / fvif] / i
