Total Value
Key Total Value in Interest Fn refers to an optional boolean that detrmines whether the value returned by the function as of the variable input date d should be just the accrued interest (plus any amortization payment) or the total value of the position that equals the sum of the accrued interest plus the applicable notional.
Default is FALSE whereby only the accrued interest is returned plus any amortization payment that might be due at the date d
If set to TRUE, the returned value equals the sum: accrued interest + applicable notional
The applicable notional is the one associated with the most recent amortization date as seen from the the variable input date d to the function here as described in detail at Notional
