Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

Public Shared Function ToString ( _
	value As Single, _
	provider As IFormatProvider _
) As String
Dim value As Single 
Dim provider As IFormatProvider 
Dim returnValue As String 

returnValue = Convert.ToString(value, _


Type: System.Single

The single-precision floating-point number to convert.

Type: System.IFormatProvider

An object that supplies culture-specific formatting information.

Return Value

Type: System.String
The string representation of value.

This implementation is identical to Single.ToString(IFormatProvider).

The following example converts each element in an array of Single values to its equivalent string representation in four different cultures.

' Define an array of numbers to display. 
Dim numbers() As Single = { -1.5345e16, -123.4321, 19092.123, _
                            1.1734231911290e16 }
' Define the culture names used to display them. 
Dim cultureNames() As String = { "en-US", "fr-FR", "ja-JP", "ru-RU" }

For Each number As Single In numbers
   Console.WriteLine("{0}:", Convert.ToString(number, _
   For Each cultureName As String In cultureNames
      Dim culture As New System.Globalization.CultureInfo(cultureName)
      Console.WriteLine("   {0}: {1,20}", _
                        culture.Name, Convert.ToString(number, culture))
' The example displays the following output: 
'    -1.5345E+16: 
'       en-US:          -1.5345E+16
