Rounding Error

[Guest]

Excel has a rounding error. When rounding 2.5 it returns 3. However, the basic rules of rounding states that when the digit following the number to be rounded is 5 you always round to an even number. In other Microsoft Tools this does not occur. For example, if you perform the following two computations in excel and Visual Basic, Visual Basic will give you the correct answer. Is there another function that can be used to resolve this problem

The correct answer
4=Round(2+.5, 0) * 2

The incorrect answer
6=Round(2+.5, 0) * 2

Sub Demo()
Debug.Print Round(2.5, 0)
Debug.Print WorksheetFunction.Round(2.5, 0)

'Banker Rounding Also
Debug.Print CLng(2.5)
Debug.Print CLng(3.5)
End Sub

As noted under your re-post to
microsoft.public.excel.worksheet.functions, you can write a UDF to
access the VBA round from the worksheet

has relevant suggestions.

It is generally sufficient to post a question in only one excel group,
since most of us frequent all of the groups. If a post is really
relevant for multiple groups, please address only one query to all the
relevant groups, to avoid our duplicating each others efforts.
