对于浮点数类型,std::to_string 可能产生不期待的结果,因为返回的字符串中的有效位数能为零,见示例。 返回值可以明显地有别于 std::cout 所默认打印的结果,见示例。 std::to_string 由于格式化目的依赖当前 C 本地环境,从而从多个线程同时调用 std::to_string 可能会导致调用的部分序列化结果。 对整数类型...

I am a bit lost on why string_t is different between linux and windows. My current issue is that I have a boot::filesystem::path that I can convert to a std::wstring and that I would like to put in a CppRestSDK Json. How can I do that ? On Linux it complains that there is...
