定义于头文件 <locale>
public:
char_type thousands_sep() const;
(1)
protected:
virtual char_type do_thousands_sep() const;
(2)
1) 公开成员函数,调用最终导出类的成员函数 do_thousands_sep
2) 返回在分析或格式化货币值整数部分时用作分隔符的字符。

[编辑] 返回值

用作千分隔符的 char_type 类型对象。在常用美国本地环境中,此为 ','L','

[编辑] 示例

#include <locale>
#include <iostream>
#include <iomanip>
#include <iterator>
struct space_out : std::moneypunct<char> {
    pattern do_pos_format()      const { return { {value, none, none, none} };}
    int do_frac_digits()         const { return 0; }
    char_type do_thousands_sep() const { return ' ';}
    string_type do_grouping()    const { return "\002";}
};
int main()
{
    std::cout.imbue(std::locale("en_US.UTF-8"));
    std::cout << "american locale: " << std::showbase
              << std::put_money(12345678.0)<< '\n';
 
    std::cout.imbue(std::locale(std::cout.getloc(), new space_out));
    std::cout << "locale with modified moneypunct: "
              << std::put_money(12345678.0)<< '\n';
}

输出:

american locale: $123,456.78
locale with modified moneypunct: 12 34 56 78
