okay bestie, this is the std::numpunct_byname< _CharT > page — manual name 3cxx, folded in right here so we are not copying the duplicated header line. It's giving libstdc++ documentation, and we're keeping every detail, periodt. 🦋

💅 decimal_point

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 numpunct<char_type>::do_decimal_point().

Returns: char_type representing a decimal point.

References: std::numpunct< _CharT >::do_decimal_point().

💅 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().

💅 do_falsename

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().

💅 do_grouping

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().

💅 do_thousands_sep

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().

💅 do_truename

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().

💅 falsename

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().

💅 grouping

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.

Every char in that returned string gets read as an integer, not as a character. Those integers are how many digits go in a group. The first char is the least significant group's digit count. If a char is negative, that means unlimited digits for the group. If more chars from the string are needed to group a number, the last char gets 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.

References: std::numpunct< _CharT >::do_grouping().

💅 thousands_sep

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 numpunct<char_type>::do_thousands_sep().

Returns: char_type representing a thousands separator.

References: std::numpunct< _CharT >::do_thousands_sep().

💅 truename

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.

References: std::numpunct< _CharT >::do_truename().
