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
