The requirements and result of the Fore.NET example execution match with those in the Fore example.

Imports Prognoz.Platform.Interop.MathFin;
…
Public Shared Sub Main(Params: StartParams);
Var
    r: double;
    Math: MathClass = New MathClass();
Begin
    r := Math.Log(8,2);
    System.Diagnostics.Debug.WriteLine(r);
End Sub;
