Class NumberOfPeriods

java.lang.Object
  |
  +--com.cedarspring.tvm.NumberOfPeriods

All Implemented Interfaces:

java.io.Serializable

final class NumberOfPeriods

extends java.lang.Object

implements java.io.Serializable

Number of Periods
Periods are evenly-spaced intervals of time. They are intentionally not stated in years since each interval must correspond to an interest compounding period.

This class will:

• Store the number of periods
• Calculate a new number of periods value given present value, future value, payment, and interest rate.
