[SecuritySafeCriticalAttribute]
public string ToString(
	IFormatProvider provider
)

Parameters

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".

NoteNote:

Because the Single data type is not supported on the Macintosh OS X operating system, the string representation of a Single value may be different from those of the other .NET Framework numeric types that are supported by OS X.

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.
