ACC1x: Problem Exporting "Single" Numeric Data to MS Excel

• Microsoft Access versions 1.0, 1.1

SYMPTOMS

You may be unable to export numeric data to Microsoft Excel if the Microsoft Access data has a Number data type, a Single field size, and a fixed format. When you export the table, the numbers lose their formatting and are altered slightly.

RESOLUTION

Format the data stored as Number-Single in Microsoft Access as "fixed - 2 decimal places" in Microsoft Excel. All the data stored as Number-Single in Microsoft Access is also stored as Number-Double.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Access versions 1.0 and 1.1. This problem no longer occurs in Microsoft Access version 2.0.
