template<typename _CharT > char_type std::numpunct< _CharT >::decimal_point
() const [inline], [inherited]
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.
References std::numpunct< _CharT >::do_decimal_point().
template<typename _CharT > virtual char_type std::numpunct< _CharT
>::do_decimal_point () const [inline], [protected], [virtual],
[inherited]
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.
Referenced by std::numpunct< _CharT >::decimal_point().
template<typename _CharT > virtual string_type std::numpunct< _CharT
>::do_falsename () const [inline], [protected], [virtual],
[inherited]
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.
Referenced by std::numpunct< _CharT >::falsename().
template<typename _CharT > virtual string std::numpunct< _CharT
>::do_grouping () const [inline], [protected], [virtual],
[inherited]
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.
Referenced by std::numpunct< _CharT >::grouping().
template<typename _CharT > virtual char_type std::numpunct< _CharT
>::do_thousands_sep () const [inline], [protected], [virtual],
[inherited]
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.
Referenced by std::numpunct< _CharT >::thousands_sep().
template<typename _CharT > virtual string_type std::numpunct< _CharT
>::do_truename () const [inline], [protected], [virtual],
[inherited]
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_type std::numpunct< _CharT >::falsename
() const [inline], [inherited]
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 > string std::numpunct< _CharT >::grouping ()
const [inline], [inherited]
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_type std::numpunct< _CharT >::thousands_sep
() const [inline], [inherited]
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.
References std::numpunct< _CharT >::do_thousands_sep().
template<typename _CharT > string_type std::numpunct< _CharT >::truename ()
const [inline], [inherited]
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.
