Workbook.AccuracyVersion Property (Excel)

Specifies whether certain worksheet functions use the latest accuracy algorithms to calculate their results. Read/write

Version Added: Excel 2010

expression .AccuracyVersion

expression A variable that represents a Workbook object.

Return Value

Integer

By default, some of the worksheet functions from Excel 2007 and earlier versions of Excel use new algorithms that increase their accuracy. However, in some cases, the new algorithms decrease the performance of these functions relative to their performance in Excel 2007 and earlier versions of Excel. To specify that these worksheet functions use the older algorithms to increase their performance, set the AccuracyVersion property to 1. The following table describes the possible settings for the AccuracyVersion property.

Setting

Description

0

Use the latest, most accurate algorithms (default)

1

Use Excel 2007 or earlier version algorithms

2

Use Excel 2010 algorithms

Note Note

Setting the AccuracyVersion property to a value other than 0, 1, or 2 will result in undefined behavior.

The following table summarizes which functions are affected by setting the AccuracyVersion property to 1. The functions that are listed in the "Functions not affected" column will always use the latest accuracy algorithms or were not changed in Excel 2010. For function names that include a period (.) in their names, to determine the name of the corresponding function implemented in VBA as a method of the WorksheetFunction object, substitute the underscore character ( _ ) for the period. For example, the VBA method that corresponds to the BETA.DIST function is the Beta_Dist method.

The following example sets the affected worksheet functions to use the older algorithms to calculate their results.

ActiveWorkbook.AccuracyVersion = 1
