Detailed Description

template<typename _CharT, typename _OutIter>
class std::num_put< _CharT, _OutIter >

Facet for converting numbers to strings.

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.

Numeric formatting.

Formats the pointer value v and inserts it into a stream. It does so by calling num_put::do_put().

This function formats v as an unsigned long with ios_base::hex and ios_base::showbase set.

fill Char_type to use for filling.
v Value to format and insert.
Returns:

) 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().

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.

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().
