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.

Parameters __refs Refcount to pass to the base class. template std::numpunct< _CharT >::numpunct (__cache_type * __cache, size_t __refs = 0) [inline], [explicit] Internal constructor. Not for general use. This is a constructor for use by the library itself to set up the predefined locale facets. Parameters __cache __numpunct_cache object. __refs Refcount to pass to the base class. template std::numpunct< _CharT >::numpunct (__c_locale __cloc, size_t __refs = 0) [inline], [explicit] Internal constructor. Not for general use. This is a constructor for use by the library itself to set up new locales.

Member Function Documentation template 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::do_decimal_point(). Returns char_type representing a decimal point. References std::numpunct< _CharT >::do_decimal_point(). template 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. Referenced by std::numpunct< _CharT >::decimal_point(). template 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. Referenced by std::numpunct< _CharT >::falsename(). template 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. Referenced by std::numpunct< _CharT >::grouping(). template 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. Referenced by std::numpunct< _CharT >::thousands_sep(). template 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(). template 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::do_falsename(). Returns string_type representing printed form of false. References std::numpunct< _CharT >::do_falsename(). template 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::do_grouping(). Returns string representing grouping specification.
