truncation/rounding bug with write.csv
To my surprise, I can confirm on Windows 10 using R 3.4.3 . As tail is not
recognized by Windows cmd, I replaced with:
system('powershell -nologo "& "Get-Content -Path temp.csv -Tail 1')
The last line shows only 7 digits after the decimal, whereas the first have
15 digits after the decimal. I agree with Dirk though, 1.6Gb csv files are
not the best way to work with

truncation/rounding bug with write.csv
Hello, I have looked on https://www.r-project.org/bugs.html , but it seems
that this is the only way to do it.
The issue is that the precision used by write.csv is on consistant for big
files. See the following code:
First I create a large dataframe filled with random uniform values. Then I
write it to .csv and print out the first and last lines.
df = data.frame(replicate(100, runif(1000000,
