XL2000: Certain Functions Calculate Differently in Early Versions of Excel

ID: Q224183

The information in this article applies to:

Microsoft Excel 2000

SYMPTOMS

When you use certain functions, you may receive a different value depending on the version of Microsoft Excel that you are using.

CAUSE

This behavior occurs when the following conditions are true:

You create a workbook in Microsoft Excel for Windows 95, version 7.0 or earlier.

You use one of the following functions and set the basis parameter to 2:
```
YIELD
ODDFYIELD
ODDFPRICE 
```

You open the workbook in Microsoft Excel 2000.

This behavior also occurs when you create a workbook in Microsoft Excel 2000 and save it in the Microsoft Excel 95/5.0 format. When the workbook is opened in Microsoft Excel 95, or earlier, these functions return a different value.

MORE INFORMATION

The method used to calculate these functions when the basis parameter is set to 2 was changed after Microsoft Excel for Windows 95, version 7.0 to produce more accurate values than in earlier versions of Microsoft Excel. Basis is the type of day count basis used by the function and is defined in the following table:

Basis Day count basis

0 or omitted US (NASD)30/360

1 Actual/actual

2 Actual/360

3 Actual/365

4 European 30/360

Because these functions were improved, they return different values than in Microsoft Excel 7.0 and earlier. Additionaly, if a workbook that was created in Microsoft Excel 5.0 or 7.0 is opened in Microsoft Excel 2000, the results from Microsoft Excel 5.0 or 7.0 may still be displayed. Even if the workbook is saved in Microsoft Excel 2000, closed and then reopened in Microsoft Excel 2000, the original values may still persist. Also, a recalculation on the workbook by pressing F9 may not resolve the issue. Microsoft Excel will not recalculate to show the correct value until either the formula is edited, the source cells change, or the entire workbook is recalculated.

To fully recalculate all formulas use one of the following methods:

Use the Calculate Full toolbar button to recalculate all cells in the active workbook. To use this button, you must first add it to a toolbar. When you click this button, Excel 2000 completely recalculates the active workbook, including all dependent and independent formulas.

Press CTRL+ALT+F9. When you use this key combination, Microsoft Excel completely recalculates all cells in all open workbooks.

Create and run a Microsoft Visual Basic for Application level Sub procedure to recalculate all cells in all open workbooks.

The following sample procedure will recalculate all values in the Excel 2000 workbook each time it is opened. Note that this procedure recalculates the workbook only once each time it is opened.


   Private Sub Workbook_Open()
       Application.CalculateFull 
   End Sub

NOTE: Do not attempt to use a Worksheet_Activate or a Worksheet_Calculate procedure to recalculate the values. If you do this, a recursive process begins, and Microsoft Excel performs very slowly. For example, do not use the following procedures:


   Private Sub Worksheet_Activate()
       Application.CalculateFull 
   End Sub

-or-


   Private Sub Worksheet_Calculate()
       Application.CalculateFull 
   End Sub

The following steps demonstrate the issue with the YIELD function.

Type the following data in a new workbook in Microsoft Excel for Windows 95, version 7.0 or earlier:
```
A1: 2/18/99
A2: 6/16/02
A3: .11875
A4: 71
A5: 100
A6: 1
A7: 2
A8: =YIELD(A1,A2,A3,A4,A5,A6,A7) 
```
The value in cell A8 is 0.257365886.

Save the workbook as Test.xls and close Microsoft Excel.

Start Microsoft Excel 2000 and open the Test.xls workbook. Press CTRL+ALT+F9 to recalculate the workbook. The value in cell A8 is now 0.257726542.
