Hello list,
I'm just getting started with R, and I'm trying to determine how R
treats large numbers that have decimals. Take the following two examples:
> x <- c(999999999999999.9)
> sprintf("%.5f",x)
[1] "999999999999999.87000"
> y <- c(9999999999999999.9)
> sprintf("%.5f",y)
[1] "10000000000000000.00000"
I realize that I have no idea what I'm doing as far as using R is
concerned, but maybe someone can tell me what would be the best way to
input/output numbers such that they don't get rounded off in unexpected
ways. I've been searching online and looking through various R manuals,
but I haven't found anything that really clarifies this so far...
Thanks in advance for any advice,
Mike
