将time_point转换为float

Question

我是这个

std::chrono::high_resolution_clock::time_point mElapsedTime;

我想将此time_point和另一个time_point之间的差异转换为浮点数，这可能吗？

Answer 1

您可以使用duration cast

std::chrono::duration<float, std::milli> diff = mElapsedTime - mStartedTime;
//access the float with .count
std::cout<<diff.count()<<'\n';
