[R] Pb with date time sequence with period<1sec

I'd like to create a date-time seq with a period of 0.05 s, over several

# try :
time<-seq(from=start, by=0.05, length.out = 86400*20*3)
# result is 0.04999995 and not 0.05 as expected

But If I am looking at the sequence, the seconds are not separated by 0.05,
but by something very close (0.04999995). Same pb if I want to add a
fraction of seconds to a date-time object :

# try :
# result is 0.04999995 and not 0.05 as expected

Any idea to solve this pb ?

Thank you in advance !
