std::chrono::floor(std::chrono::time_point)
Defined in header <chrono> | | |
|---|---|---|
template <class ToDuration, class Clock, class Duration> constexpr time_point<Clock, ToDuration> floor(const time_point<Clock, Duration>& tp); | | (since C++17) |
返回最大时间点t可在ToDuration较小的或等于tp...
该函数不参与重载解析，除非ToDuration是std::chrono::duration...
参数
tp | - | time point to round down |
|---|
返回值
d使用类型的持续时间舍入到下一个时间点。ToDuration...
可能的实施
模板<class T>结构是[医]持续时间：STD：：false[医]类型{}；模板<类Rep，类周期>结构是[医]持续时间<std：：time：：time<rep，time>>：std：：true[医]类型{}；模板<class到，类时钟，类FromDuration，class=std：：Enable[医]如果[医]T<IS[医]持续时间<To>{}>>std：：time：：time[医]点<时钟，到>地板%28 const std：：time：：time[医]点<时钟，倒转>&tp%29{返回std：：chrono：：time[医]点<时钟，到>{std：：time：：地板<To>%28 tp.time[医]自[医]EIRCH%28%29%29}；}

例
另见
time_point_cast | converts a time point to another time point on the same clock, with a different duration (function template) |
|---|---|
ceil(std::chrono::time_point) (C++17) | converts a time_point to another, rounding up (function template) |
round(std::chrono::time_point) (C++17) | converts a time_point to another, rounding to nearest, ties to even (function template) |
floor(std::chrono::duration) (C++17) | converts a duration to another, rounding down (function template) |
floor | nearest integer not greater than the given value (function) |
