Detailed Description
template<typename _CharT, typename _OutIter>class std::num_put< _CharT, _OutIter >
Primary class template num_put.
This facet encapsulates the code to convert a number to a string. It is used by the
ostream numeric insertion operators.
The num_put 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 the num_put facet.

template<typename _CharT , typename _OutIter > iter_type std::num_put< _CharT, _OutIter >::put
(iter_type__s, ios_base &__io, char_type__fill, bool__v) const [inline]
Numeric formatting. Formats the boolean v and inserts it into a stream. It does so by
calling num_put::do_put().
If ios_base::boolalpha is set, writes ctype<CharT>::truename() or
ctype<CharT>::falsename(). Otherwise formats v as an int.
Parameters:
__s Stream to write to.
__io Source of locale and flags.
__fill Char_type to use for filling.
__v Value to format and insert.
Returns:
Iterator after writing.

template<typename _CharT , typename _OutIter > iter_type std::num_put< _CharT, _OutIter >::put
(iter_type__s, ios_base &__io, char_type__fill, long__v) const [inline]
Numeric formatting. Formats the integral value v and inserts it into a stream. It does so
by calling num_put::do_put().
Formatting is affected by the flag settings in io.
The basic format is affected by the value of io.flags() & ios_base::basefield. If equal to
ios_base::oct, formats like the printf o specifier. Else if equal to ios_base::hex,
formats like x or X with ios_base::uppercase unset or set respectively. Otherwise, formats
like d, ld, lld for signed and u, lu, llu for unsigned values. Note that if both oct and
hex are set, neither will take effect.
If ios_base::showpos is set, '+' is output before positive values. If ios_base::showbase
is set, '0' precedes octal values (except 0) and '0[xX]' precedes hex values.
Thousands separators are inserted according to numpunct::grouping() and
numpunct::thousands_sep(). The decimal point character used is numpunct::decimal_point().
If io.width() is non-zero, enough fill characters are inserted to make the result at least
that wide. If (io.flags() & ios_base::adjustfield) == ios_base::left, result is padded at
the end. If ios_base::internal, then padding occurs immediately after either a '+' or '-'
or after '0x' or '0X'. Otherwise, padding occurs at the beginning.
Parameters:
__s Stream to write to.
__io Source of locale and flags.
__fill Char_type to use for filling.
__v Value to format and insert.
Returns:
Iterator after writing.

(iter_type__s, ios_base &__io, char_type__fill, double__v) const [inline]
Numeric formatting. Formats the floating point value v and inserts it into a stream. It
does so by calling num_put::do_put().
Formatting is affected by the flag settings in io.
The basic format is affected by the value of io.flags() & ios_base::floatfield. If equal
to ios_base::fixed, formats like the printf f specifier. Else if equal to
ios_base::scientific, formats like e or E with ios_base::uppercase unset or set
respectively. Otherwise, formats like g or G depending on uppercase. Note that if both
fixed and scientific are set, the effect will also be like g or G.
The output precision is given by io.precision(). This precision is capped at
numeric_limits::digits10 + 2 (different for double and long double). The default precision
is 6.
If ios_base::showpos is set, '+' is output before positive values. If ios_base::showpoint
is set, a decimal point will always be output.
Thousands separators are inserted according to numpunct::grouping() and
numpunct::thousands_sep(). The decimal point character used is numpunct::decimal_point().
