Detailed Description
template<typename _CharT>
class std::numpunct< _CharT >
Numpunct facet.
This facet stores several pieces of information related to printing and scanning numbers, such as the decimal point character. It takes a template parameter specifying the char type. The numpunct facet is used by streams for many I/O operations involving numbers.
The numpunct template uses protected virtual functions to provide the actual results. The public accessors forward the call to the virtual functions. These virtual functions are hooks for developers to implement the behavior they require from a numpunct facet.

Member Function Documentation
| char_type std::numpunct< _CharT >::decimal_point | ( | ) | const [inline] |
Return decimal point character.
This function returns a char_type to use as a decimal point. It does so by returning returning numpunct<char_type>::do_decimal_point().
- Returns:
- char_type representing a decimal point.
Definition at line 1701 of file locale_facets.h.
| virtual char_type std::numpunct< _CharT >::do_decimal_point | ( | ) | const [inline, protected, virtual] |
Return decimal point character.
Returns a char_type to use as a decimal point. This function is a hook for derived classes to change the value returned.
- Returns:
- char_type representing a decimal point.

| virtual string_type std::numpunct< _CharT >::do_falsename | ( | ) | const [inline, protected, virtual] |
Return string representation of bool false.
Returns a string_type containing the text representation for false bool variables. This function is a hook for derived classes to change the value returned.
- Returns:
- string_type representing printed form of false.

| virtual string std::numpunct< _CharT >::do_grouping | ( | ) | const [inline, protected, virtual] |
Return grouping specification.
Returns a string representing groupings for the integer part of a number. This function is a hook for derived classes to change the value returned.
- See also:
- grouping() for details.
- Returns:
- String representing grouping specification.

| virtual char_type std::numpunct< _CharT >::do_thousands_sep | ( | ) | const [inline, protected, virtual] |
Return thousands separator character.
Returns a char_type to use as a thousands separator. This function is a hook for derived classes to change the value returned.
- Returns:
- char_type representing a thousands separator.

| virtual string_type std::numpunct< _CharT >::do_truename | ( | ) | const [inline, protected, virtual] |
Return string representation of bool true.
Returns a string_type containing the text representation for true bool variables. This function is a hook for derived classes to change the value returned.
- Returns:
- string_type representing printed form of true.

Referenced by std::numpunct< _CharT >::truename().
| string_type std::numpunct< _CharT >::falsename | ( | ) | const [inline] |
Return string representation of bool false.
This function returns a string_type containing the text representation for false bool variables. It does so by calling numpunct<char_type>::do_falsename().
- Returns:
- string_type representing printed form of false.
Definition at line 1771 of file locale_facets.h.
| string std::numpunct< _CharT >::grouping | ( | ) | const [inline] |
Return grouping specification.
This function returns a string representing groupings for the integer part of a number. Groupings indicate where thousands separators should be inserted in the integer part of a number.
Each char in the return string is interpret as an integer rather than a character. These numbers represent the number of digits in a group. The first char in the string represents the number of digits in the least significant group. If a char is negative, it indicates an unlimited number of digits for the group. If more chars from the string are required to group a number, the last char is used repeatedly.
For example, if the grouping() returns "\003\002" and is applied to the number 123456789, this corresponds to 12,34,56,789. Note that if the string was "32", this would put more than 50 digits into the least significant group if the character set is ASCII.
The string is returned by calling numpunct<char_type>::do_grouping().
- Returns:
- string representing grouping specification.

| char_type std::numpunct< _CharT >::thousands_sep | ( | ) | const [inline] |
Return thousands separator character.
This function returns a char_type to use as a thousands separator. It does so by returning returning numpunct<char_type>::do_thousands_sep().
- Returns:
- char_type representing a thousands separator.
Definition at line 1714 of file locale_facets.h.
| string_type std::numpunct< _CharT >::truename | ( | ) | const [inline] |
Return string representation of bool true.
This function returns a string_type containing the text representation for true bool variables. It does so by calling numpunct<char_type>::do_truename().
- Returns:
- string_type representing printed form of true.
