Strings.FormatCurrency(Object, Int32, TriState, TriState, TriState) Method

Definition

Returns an expression formatted as a currency value using the currency symbol defined in the system control panel.

public static string FormatCurrency (object? Expression, int NumDigitsAfterDecimal = -1, Microsoft.VisualBasic.TriState IncludeLeadingDigit = Microsoft.VisualBasic.TriState.UseDefault, Microsoft.VisualBasic.TriState UseParensForNegativeNumbers = Microsoft.VisualBasic.TriState.UseDefault, Microsoft.VisualBasic.TriState GroupDigits = Microsoft.VisualBasic.TriState.UseDefault);

static member FormatCurrency : obj * int * Microsoft.VisualBasic.TriState * Microsoft.VisualBasic.TriState * Microsoft.VisualBasic.TriState -> string
Public Function FormatCurrency (Expression As Object, Optional NumDigitsAfterDecimal As Integer = -1, Optional IncludeLeadingDigit As TriState = Microsoft.VisualBasic.TriState.UseDefault, Optional UseParensForNegativeNumbers As TriState = Microsoft.VisualBasic.TriState.UseDefault, Optional GroupDigits As TriState = Microsoft.VisualBasic.TriState.UseDefault) As String

Parameters

Expression
Object

Required. Expression to be formatted.

NumDigitsAfterDecimal
Int32

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

IncludeLeadingDigit
TriState

Optional. TriState enumeration that indicates whether or not a leading zero is displayed for fractional values. See "Remarks" for values.

UseParensForNegativeNumbers
TriState

Optional. TriState enumeration that indicates whether or not to place negative values within parentheses. See "Remarks" for values.

GroupDigits
TriState

Optional. TriState enumeration that indicates whether or not numbers are grouped using the group delimiter specified in the computer's regional settings. See "Remarks" for values.

Returns

An expression formatted as a currency value using the currency symbol defined in the system control panel.

Exceptions

Number of digits after decimal point is greater than 99.

Type is not numeric.

Examples

The following example illustrates the use of the FormatCurrency function.

Dim testDebt As Double = -4456.43
Dim testString As String
' Returns "($4,456.43)".
testString = FormatCurrency(testDebt, , , TriState.True, TriState.True)

Remarks

When one or more optional arguments are omitted, the computer's matching regional-settings values are used instead.

The position of the currency symbol relative to the currency value is determined by the system's regional 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, except leading zero, which comes from the Number tab.

The IncludeLeadingDigit, UseParensForNegativeNumbers, and GroupDigits arguments take the following TriState enumeration values.

Value Description
TriState.True True
TriState.False False
TriState.UseDefault The computer's regional settings
