round up a number to 10^4
Could you divide by your desired order of magnitude, use ceiling and then re-multiply? Michael

Hi all, I have a list of numbers, e.g., X = c(60593.23, 71631.17, 75320.1), and want to round them so the output is Y = c(60000, 80000, 80000).
Under what notion of "rounding" would that be the result?
I tried Y<-round(X,-4), but it gives me Y = c(60000, 70000, 80000). Do anybody know how to round up a number to 10^4? Thank you in advance.
