std::chrono::treat_as_floating_point 特征帮助确定时长是否能转换成拥有另一种不同计次周期的时长。 两个时长间的隐式转换通常依赖于时长的计次周期。然而若 std::chrono::treat_as_floating_point<Rep>::value 为Template:true 则不管计次周期如何,均可发生隐式转换。
c++c++17floating-point-conversion 19 根据https://en.cppreference.com/w/cpp/compiler_support/17,目前尚无主要供应商支持浮点版本的std::to_chars和std::from_chars。我理解正确地格式化浮点数是非常复杂的,但是C库中存在实现。然而,这些实现受环境影响,这也是将std::to_chars和std::from_chars添加到标准中...

移动通信标准协议ieeestd802.11b 802.11b has a maximum raw data rate of 11 Mbit/s and uses the same CSMA/CA media access method defined in the original standard. Due to the CSMA/CA protocol overhead, in practice the maximum 802.11b throughput that an application can achieve is about 5.9 Mbi...
