Convert.ToString Method (Single)

.NET Framework 1.1

Converts the value of the specified single-precision floating point number to its equivalent String representation.

[Visual Basic]
Overloads Public Shared Function ToString( _
   ByVal value As Single _
) As String
[C#]
public static string ToString(
 float value
);
[C++]
public: static String* ToString(
 float value
);
[JScript]
public static function ToString(
   value : float
) : String;

Parameters

value
A single-precision floating point number.

Return Value

The String equivalent of the value of value.

Remarks

This implementation is identical to Single.ToString.

Example

[Visual Basic, C#, C++] The following code sample illustrates the conversion of a Single to a String, using ToString.

[Visual Basic] 
Public Sub ConvertStringFloat(ByVal stringVal As String)
    Dim singleVal As Single = 0

    Try
        singleVal = System.Convert.ToSingle(singleVal)
        System.Console.WriteLine("The string as a single is {0}.", _
                                  singleVal)
    Catch exception As System.OverflowException
        System.Console.WriteLine( _
            "Overflow in string-to-single conversion.")
    Catch exception As System.FormatException
        System.Console.WriteLine( _
            "The string is not formatted as a Single.")
    Catch exception As System.ArgumentException
        System.Console.WriteLine("The string is null.")
    End Try

    ' Single to string conversion will not overflow.
    stringVal = System.Convert.ToString(singleVal)
    System.Console.WriteLine("The single as a string is {0}.", _
                              stringVal)
End Sub

[C#] 
public void ConvertStringFloat(string stringVal) {
    float floatVal = 0;
    
    try {
        floatVal = System.Convert.ToSingle(stringVal);
        System.Console.WriteLine(
            "The string as a float is {0}.", floatVal);
    } 
    catch (System.OverflowException){
        System.Console.WriteLine(
            "The conversion from string-to-float overflowed.");
    }
    catch (System.FormatException) {
        System.Console.WriteLine(
            "The string is not formatted as a float.");
    }
    catch (System.ArgumentNullException) {
        System.Console.WriteLine(
            "The string is null.");
    }

    // Float to string conversion will not overflow.
    stringVal = System.Convert.ToString(floatVal);
    System.Console.WriteLine(
        "The float as a string is {0}.", stringVal);
}

[C++] 

   void ConvertStringFloat(String* stringVal)
   {
      float floatVal = 0;

      try {
         floatVal = System::Convert::ToSingle(stringVal);
         System::Console::WriteLine(S"The String* as a float is {0}.", __box(floatVal));
      } catch (System::OverflowException*) {
         System::Console::WriteLine(S"The conversion from String*-to-float overflowed.");
      } catch (System::FormatException*) {
         System::Console::WriteLine(S"The String* is not formatted as a float.");
      } catch (System::ArgumentNullException*) {
         System::Console::WriteLine(S"The String* is 0.");
      }

      // Float to String* conversion will not overflow.
      stringVal = System::Convert::ToString(floatVal);
      System::Console::WriteLine(S"The float as a String* is {0}.", stringVal);
   }
