Fore Example

To execute the example, add a link to the MathFin system assembly.

Sub UserProc;
Var

Imports Prognoz.Platform.Interop.MathFin;
…
Public Shared Sub Main(Params: StartParams);
Var
    r: double;
    Math: MathClass = New MathClass();
Begin
    r := Math.ACos(-0.5);
    System.Diagnostics.Debug.WriteLine(r);
End Sub;
