WebApr 29, 2024 · As you can see at line 19, we chose to cast the measured time to nanoseconds (although later we convert it to seconds). If you prefer, you can modify the code to use another unit of your choice, using chrono::hours, chrono::minutes, chrono::seconds, chrono::milliseconds, or chrono::microseconds. WebAug 23, 2024 · It actually gave me -0.001 milliseconds in c++ shell on one trial. The number of clock ticks per second is machine-dependent, but 100 multiplies hopefully won't take long. If it's less than one clock interval then the discrete result will be 0. Last edited on Aug 21, 2024 at 3:03pm Aug 22, 2024 at 12:35am puertas12 (64) Thanks @lastchance.
