XL98: Indexes for Methods and Collections Are Rounded (190357)


The information in this article applies to:

  • Microsoft Excel 98 Macintosh Edition
This article was previously published under Q190357

SYMPTOMS

In Microsoft Excel 98 Macintosh Edition, 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 98 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.

RESOLUTION

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. 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 different results in different versions of Microsoft Excel: 
   MsgBox Sheets(1.6).Name
In Microsoft Excel 98, 1.6 is rounded to 2; and, this line of code references the second Sheet in the Sheets collection. In Microsoft Excel version 5.0, the number 1.6 is truncated to 1; and, this line of code references the first Sheet in the Sheets collection.
