Single::ToString Method ()
Converts the numeric value of this instance to its equivalent string representation.
Assembly: mscorlib (in mscorlib.dll)
The ToString() method formats a Single value in the default ("G", or general) format of the current culture. If you want to specify a different format or culture, use the other overloads of the ToString method, as follows:
To use format | For culture | Use the overload |
|---|---|---|
Default ("G") format | A specific culture | |
A specific format | Default (current) culture | |
A specific format | A specific culture |
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 that contain 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".
The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics:
For more information about numeric format specifiers, see Standard Numeric Format Strings and Custom Numeric Format Strings.

The following example uses the default Single::ToString method to display the string representations of a number of Single values.
The following code example illustrates the use of the Parse(String^) method along with the ToString() method.
bool done = false; String^ inp; do { Console::Write( "Enter a real number: " ); inp = Console::ReadLine(); try { s = Single::Parse( inp ); Console::WriteLine( "You entered {0}.", s ); done = true; } catch ( FormatException^ ) { Console::WriteLine( "You did not enter a number." ); } catch ( Exception^ e ) { Console::WriteLine( "An exception occurred while parsing your response: {0}", e ); } } while ( !done );
