Single.ToString Method (IFormatProvider)
Converts the numeric value of this instance to its equivalent string representation using the specified culture-specific format information.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Parameters
- provider
- Type: System.IFormatProvider
An object that supplies culture-specific formatting information.
Return Value
Type: System.StringThe string representation of the value of this instance as specified by provider.
Implements
IConvertible.ToString(IFormatProvider)The return value can be PositiveInfinitySymbol, NegativeInfinitySymbol, NaNSymbol, or a string of the form:
[sign]integral-digits[.[fractional-digits]][e[sign]exponential-digits]
Optional elements are framed in square brackets ([ and ]). Elements containing the term "digits" consist of a series of numeric characters ranging from 0 to 9. The following table lists each element.
Element | Description |
|---|---|
sign | A negative sign or positive sign symbol. |
integral-digits | A series of digits specifying the integral part of the number. Integral-digits can be absent if there are fractional-digits. |
'.' | A culture-specific decimal point symbol. |
fractional-digits | A series of digits specifying the fractional part of the number. |
'e' | A lowercase character 'e', indicating exponential (scientific) notation. |
exponential-digits | A series of digits specifying an exponent. |
Some examples of the return value are "100", "-123,456,789", "123.45e+6", "500", "3.1416", "600", "-0.123", and "-Infinity".
This instance is formatted with the general numeric format specifier ("G").
The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics:

The provider parameter is an IFormatProvider implementation whose GetFormat method returns a NumberFormatInfo object. Typically, provider is a CultureInfo object or a NumberFormatInfo object. The provider parameter supplies culture-specific information used in formatting. If provider is null, the return value is formatted using the NumberFormatInfo data for the current culture.
To convert a Single value to its string representation using a specified culture and a specific format string, call the Single.ToString(String, IFormatProvider) method.
The following example displays the string representation of two Single values using CultureInfo objects that represent several different cultures.
float value; value = -16325.62015F; // Display value using the invariant culture. Console.WriteLine(value.ToString(CultureInfo.InvariantCulture)); // Display value using the en-GB culture. Console.WriteLine(value.ToString(CultureInfo.CreateSpecificCulture("en-GB"))); // Display value using the de-DE culture. Console.WriteLine(value.ToString(CultureInfo.CreateSpecificCulture("de-DE"))); value = 16034.125E21F; // Display value using the invariant culture. Console.WriteLine(value.ToString(CultureInfo.InvariantCulture)); // Display value using the en-GB culture. Console.WriteLine(value.ToString(CultureInfo.CreateSpecificCulture("en-GB"))); // Display value using the de-DE culture. Console.WriteLine(value.ToString(CultureInfo.CreateSpecificCulture("de-DE"))); // This example displays the following output to the console: // -16325.62015 // -16325.62015 // -16325,62015 // 1.6034125E+25 // 1.6034125E+25 // 1,6034125E+25
