The small white, about time stamp-CodePudding

Please look at the code, this is a prime number code, use timestamp UnixNano () and the time needed for this code runs, found a problem: if the value is 501 v the following number, operation result is 0, if the value is 501 v, the running result is 1000000, is a nanosecond timestamps of the minimum value is 1000000, bosses give advice or comments, thank you ~

Not the
Try using the following code

 s:=time Now () UnixNano () 
Time. Sleep time. The Nanosecond * 1)//stop 1 Nanosecond 
E:=time. Now (). UnixNano () 
FMT. Printf (" % d, % d, % d \ n ", s, e, e - s)

Bosses, according to the code you tried running results:
1578287106372698900 1578287106371698900 1000000
Dormancy 1 nanosecond or 100 w nanoseconds, or a few microseconds, a few milliseconds, as long as it is within 100 w nanosecond time number, run results nanosecond is 1000000, isn't me is a problem with the program

You are a Windows system? Windows system seems to be calculated on a 100 nanoseconds

Right, is a Windows system, it could be the system problem, 100 w nanosecond is equivalent to 1 nanoseconds, also not too long, the impact is not big, involves a question of time later I would note that there is such a thing to go, thank you very much

Right, is a Windows system, it could be the system problem, 100 w nanosecond is equivalent to 1 nanoseconds, also not too long, the impact is not big, later involves a question of time again, I'll pay attention to there is such a thing to go, thank you very much

Should be 100 w nanosecond is equivalent to 1 millisecond, got the wrong number??
