Detailed Description
template<typename_CharT>
class std::numpunct< _CharT >"Primary class template numpunct.
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.

template<typename_CharT>char_typestd::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().
Returnschar_type representing a decimal point.

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.

template<typename_CharT>virtualstringstd::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.

grouping() for details.
Returns
String representing grouping specification.

template<typename_CharT>virtualchar_typestd::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.
Returnschar_type representing a thousands separator.
Referenced by std::numpunct<_CharT>::thousands_sep().
template<typename_CharT>virtualstring_typestd::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().
template<typename_CharT>string_typestd::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.
References std::numpunct<_CharT>::do_falsename().
template<typename_CharT>stringstd::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.

template<typename_CharT>char_typestd::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.

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.
