SYMPTOMS
In Microsoft Excel 97, if you specify a decimal value for the index of a method or collection in a Visual Basic for Applications macro, the index is rounded to the nearest whole number. However, in earlier versions of Microsoft Excel, the index is truncated rather than rounded. Because of this difference, you may receive different results from different versions of Microsoft Excel.



CAUSE
Microsoft Excel 97 uses strict typing for arguments of collections and methods. If an argument is typed as an integer, decimal values that are passed to that argument are automatically rounded.

This behavior is by design of Microsoft Excel.

You should not rely on Microsoft Excel to automatically convert your decimal values for indexes. If you require that the index is to be truncated in all versions of Microsoft Excel, use the INT function: MsgBox Sheets(INT(1.6)).Name If you require that the index is to be rounded in all versions of Microsoft Excel, use the CInt function: MsgBox Sheets(CInt(1.6)).Name



MORE INFORMATION
The following sample demonstrates a situation where you receive conflicting results in different versions of Microsoft Excel. MsgBox Sheets(1.6).Name In Microsoft Excel 97, 1.6 is rounded to 2; and, this line of code will reference the second Sheet in the Sheets collection. In Microsoft Excel versions 5.0 and 7.0, the number 1.6 is truncated to 1; and, this line of code references the first Sheet in the Sheets collection.
