class std::numpunct_byname< _CharT >"class numpunct_byname [22.2.3.2].

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.

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.

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.

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.

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.

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.

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().

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.

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.
