constexpr rep count()const;		(since C++11)

Returns the number of ticks for this duration.

Parameters

(none)

Return value

The number of ticks for this duration.

Example

Run this code

#include <chrono>#include <iostream>   int main(){std::chrono::milliseconds ms{3};// 3 milliseconds// 6000 microseconds constructed from 3 millisecondsstd::chrono::microseconds us =2* ms;// 30Hz clock using fractional ticksstd::chrono::duration<double, std::ratio<1, 30>> hz30(3.5);   std::cout<<"3 ms duration has "<< ms.count()<<" ticks\n"<<"6000 us duration has "<< us.count()<<" ticks\n"<<"3.5 30Hz duration has "<< hz30.count()<<" ticks\n";}

Output:

3 ms duration has 3 ticks 6000 us duration has 6000 ticks 3.5 30Hz duration has 3.5 ticks

converts a duration to another, with a different tick interval (function template)
