[edit] Parameters
(none)
[edit] Return value
The number of ticks for this duration.
[edit] Example
Run this code
#include <chrono> #include <iostream> int main() { std::chrono::milliseconds ms{3}; // 3 milliseconds // 6000 microseconds constructed from 3 milliseconds std::chrono::microseconds us = 2 * ms; // 30Hz clock using fractional ticks std::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
