do_decimal_point。[edit] 返回值
类型为 CharT 的对象，保存着小数点字符。
[edit] 示例
运行这段代码
#include <iomanip> #include <iostream> #include <locale> void show_dpt(const char* locname) { std::locale loc(locname); std::cout.imbue(loc); std::cout << locname << " decimal point is '" << std::use_facet<std::moneypunct<char>>(loc).decimal_point() << "' for example: " << std::showbase << std::put_money(123); if (std::use_facet<std::moneypunct<char>>(loc).frac_digits() == 0) std::cout << " (does not use frac digits)"; std::cout << '\n'; } int main() { show_dpt("en_US.utf8"); show_dpt("ja_JP.utf8"); show_dpt("sv_SE.utf8"); show_dpt("de_DE.utf8"); }
输出
en_US.utf8 decimal point is '.' for example: $1.23 ja_JP.utf8 decimal point is '.' for example: ￥123 (does not use frac digits) sv_SE.utf8 decimal point is ',' for example: 1,23 kr de_DE.utf8 decimal point is ',' for example: 1,23 €
