Currency decimal places in Access 2007

Hi

I need to set a currency field in Access to 6 decimal places ie £1.123456.  However when I do this entries are rounded to 4 decimal places eg £1.123456 becomes £1.123500

Does anyone know why this is happening and how to get around it?

Cheers

Ken

Try something like this.

'Round the number to the third decimal
If Len(DeciPart) > 6 Then
DeciPart = Round(DeciPart, 5)
'If number only has five decimal, then no need to go further
ElseIf Len(DeciPart) <= 7 Then
GoTo ender
End If

ender:
'Check DeciPart for correct format
If Left(DeciPart, 1) <> 0 Then DeciPart = 0 & DeciPart
Exit Sub

That looks great but why is setting the currecny field to 6 decimal places in the table not working?  Adding code to everywhere there is a currency input field in this db seems an unnecesary complication

Ken,By definition, the Currency data type stores four decimal places.  You cannot get it to store more or fewer decimal places than that, although you can change how Access displays those values.BTW, the property you were adjusting for number of decimal places is relevant for displaying data only, and has no impact on how Access actually stores the data.None of the native Access data types allow you to specify the number of decimal places that are actually stored.  If you want that capability, you must go to a server-based RDBMS such as SQL Server, Oracle, MySQL, etc.Patrick

To make the change on the table level, change the data type to number, the format to currency, and set the field size to double.  That will cause the field to retain its decimal places.
