io.starter.formats.XLS.formulas.FunctionHandler

public class FunctionHandler
extends Object

Function Handler takes an array of PTG's with a header PtgFunc or PtgFuncVar, calcuates those ptgs in the determined way, then return a relevant PtgValue Descriptions of these functions are available on the msdn site, http://msdn.microsoft.com/library/default.asp?url=/library/en-us/office97/html/S88F9.asp

* Your standard big case statement, calling methods based on what the funkid is. * You will notice that these are seperated out into packages based on the MS * documentation (Link above). Each package calls a different class full of * static method calls. There are a lot of these :-) * * PLEASE: Remove function from comment list when you enable it!!!! * *
