Class representing a perpetuity-due — a stream of fixed payments made at the beginning of each period indefinitely.
The present value (PV) of a perpetuity-due is calculated as: PV = P / i × (1 + i) = P × (1 + i) / i
Where:
The fixed payment amount per period. Must be positive.
The interest rate per period (decimal form, e.g. 0.05 for 5%). Must be positive.
Gets the current interest rate per period.
Gets the current payment amount.
Calculates the present value of the perpetuity-due.
The present value, using PV = P × (1 + i) / i
