Convert.ToString Method (Single, IFormatProvider)

Converts the value of the specified single-precision floating-point number to its equivalent string representation, using the specified culture-specific formatting information.

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

public static string ToString(
	float value,
	IFormatProvider provider
)

Parameters

value
Type: System.Single

The single-precision floating-point number to convert.

provider
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. 
float[] numbers = { -1.5345e16f, -123.4321f, 19092.123f, 1.1734231911290e16f };
// Define the culture names used to display them.
string[] cultureNames = { "en-US", "fr-FR", "ja-JP", "ru-RU" };

foreach (float number in numbers)
{
   Console.WriteLine("{0}:", Convert.ToString(number,
                             System.Globalization.CultureInfo.InvariantCulture));
   foreach (string cultureName in cultureNames)
   {
      System.Globalization.CultureInfo culture = new System.Globalization.CultureInfo(cultureName);
      Console.WriteLine("   {0}: {1,20}",
                        culture.Name, Convert.ToString(number, culture));
   }
   Console.WriteLine();
}   
// The example displays the following output: 
//    -1.5345E+16: 
//       en-US:          -1.5345E+16 
//       fr-FR:          -1,5345E+16 
//       ja-JP:          -1.5345E+16 
//       ru-RU:          -1,5345E+16 
//     
//    -123.4321: 
//       en-US:            -123.4321 
//       fr-FR:            -123,4321 
//       ja-JP:            -123.4321 
//       ru-RU:            -123,4321 
//     
//    19092.123: 
//       en-US:            19092.123 
//       fr-FR:            19092,123 
//       ja-JP:            19092.123 
//       ru-RU:            19092,123 
//     
//    1.173423191129E+16: 
//       en-US:   1.173423191129E+16 
//       fr-FR:   1,173423191129E+16 
//       ja-JP:   1.173423191129E+16
