Parameters

Expression

Required. Expression to be formatted.

NumDigitsAfterDecimal

Optional. Numeric value indicating how many places are displayed to the right of the decimal. The default value is –1, which indicates that the computer's regional settings are used.

IncludeLeadingDigit

Optional. TriState constant that indicates whether a leading 0 is displayed for fractional values. See "Settings" for values.

UseParensForNegativeNumbers

Optional. TriState constant that indicates whether to place negative values within parentheses. See "Settings" for values.

GroupDigits

Optional. TriState constant that indicates whether or not numbers are grouped using the group delimiter specified in the locale settings. See "Settings" for values.

Return Value

For more detailed information, see the Visual Basic topic FormatNumber Function (Visual Basic).

When one or more optional arguments are omitted the values for omitted arguments are provided by the locale settings.

Note
All settings information comes from the locale of the application. By default, that will be the locale set in the control panel. However, it may be changed programmatically by using the .NET Framework.

The IncludeLeadingDigit, UseParensForNegativeNumbers, and GroupDigits arguments have the following settings.

This example demonstrates the FormatNumber function.

Dim TestNumber As Integer = 45600
' Returns "45,600.00".
Dim TestString As String = FormatNumber(TestNumber, 2, , , TriState.True)
