Hi, I'd like to create a date-time seq with a period of 0.05 s, over several days.
# try : start<-strptime(nom_fich,format="%y%m%d") time<-seq(from=start, by=0.05, length.out = 86400*20*3) print(as.POSIXlt(time[2])$sec) # result is 0.04999995 and not 0.05 as expected But If I am looking at the sequence, the seconds are not separated by 0.05, but by something very close (0.04999995). Same pb if I want to add a fraction of seconds to a date-time object : # try : start<-strptime(nom_fich,format="%y%m%d") as.POSIXlt(start+0.05,origin="1970-01-01")$sec # result is 0.04999995 and not 0.05 as expected Any idea to solve this pb ?
