Remarks

Users can build custom functions used in formulas by sub-classing the Infragistics.Calculations.Engine.CalculationFunction class. Once the derived class is instaniated it must be registered by using the AddFunction method before being avilable and referenced by a formulas. Users can build a library of functions packaged in an assembly and register all the functions within the assembly by using the AddFunctionLibrary method.
