SYMPTOMS
When using the Round function in Visual Basic 6.0, a different result may be returned than when using it in a cell formula of an Excel spreadsheet.



CAUSE
The VBA Round function uses Banker's rounding while the spreadsheet cell function uses arithmetic rounding.



RESOLUTION
Write a custom function to get the desired results.



STATUS
This behavior is by design.



MORE INFORMATION
The Round function in an Excel spreadsheet uses Arithmetic rounding, which always rounds .5 up (away from 0). The Round function in Visual Basic for Applications 6, uses Banker's rounding, which rounds .5 either up or down, whichever will result in an even number.

Steps to Reproduce Behavior
  In Excel, open a new spreadsheet and type the following formula into one of the cells: =Round(2.5, 0)  The result is 3.  In Visual Basic 6.0 or other applications using VBA 6, open a new project and type the following expression into the Debug or Immediate window: ? Round(2.5, 0)  The result is 2.
