,Intrate(Settlement: DateTime; Maturity: DateTime; Investment: Double; Redemption: Double; [Basis: Integer = 0]): Double;
Intrate(Settlement: System.DateTime; Maturity: System.DateTime; Investment: double; Redemption: double; Basis: integer): double;
Settlement. The payment day on securities. Must be less than Maturity
Maturity. The security's maturity date. Must be greater than Settlement
Investment. The amount invested in securities. Must be positive.
Redemption. Amount received at maturity for a fully invested security. Must be positive.
Basis. The day calculation method used. Select a value from 0 to 4:
0. The day calculation method - American/360 days (NSAD method).
1. The day calculation method - Actual/actual.
2. The day calculation method - Actual/360 days.
3. The day calculation method - Actual/365 days.
4. The day calculation method - European 30/360 days.
The Intrate method returns the interest rate for fully invested securities.
Intrate is calculated using the following formula:
,
where:
B. The number of days in a year that depends on the selected Basis argument value.
DIM. The number of days from settlement date to maturity date.

Finance: FinanceClass = New FinanceClass();
DateTime1, DateTime2: System.DateTime;
Begin
DateTime1 := New DateTime(2008,01,01);
DateTime2 := New DateTime(2008,06,01);
r := Finance.Intrate(DateTime1, DateTime2, 1500.5, 1600.4, 0);
System.Diagnostics.Debug.WriteLine(r);
End Sub;
After executing the example the console window displays the interest rate equal to 0.16.
