In deciding on the number of digits to present, the Factbook staff assesses the accuracy of the original data and the needs of US Government officials. All of the economic data are processed by computer—either at the source or by the Factbook staff. The economic data presented in The Factbook, therefore, follow the rounding convention used by virtually all numerical software applications, namely, any digit followed by a "5" is rounded up to the next higher digit, no matter whether the original digit is even or odd. Thus, for example, when rounded to the nearest integer, 2.5 becomes 3, rather than 2, as occurred in some pre-computer rounding systems.

I am using the Factbook online and it is not working. What is wrong?
Hundreds of "Factbook" look-alikes exist on the Internet. The Factbook site at: www.cia.gov is the only official site.
When I attempt to download a PDF (Portable Document Format) map file (or some other map) the file has no image. Can you fix this?
Some of the files on The World Factbook Web site are large and could take several minutes to download on a dial-up connection. The screen might be blank during the download process.
When I open a map on The World Factbook site, it is fuzzy or granular, or too big or too small. Why?
Adjusting the resolution setting on your monitor should correct this problem.
