All the arguments, denoting money, which has to be paid (for example, saving accounts), are represented as negative numbers; all the money, which has to be received (for example, dividends), are represented as positive numbers.
Ispmt is calculated using the following formula:
To execute the example, add a link to the MathFin system assembly.
Sub UserProc;
Var
r: Double;
Begin
r := Finance.Ispmt(0.15, 1, 12, 1200);
Debug.WriteLine(r);
End Sub UserProc;
After executing the example the console window displays the percent equal to -165.
