actually, you cannot precise exact area due to sea tides. you also probably learned in school that largest island in Croatia (Yugoslavia) was Krk. but lately, the newest measurings show that they are exactly equal, or some claim that Cres is even larger.
on each island's homepage they claim that their island is the largest

National Mapping and Resource Information Authority of the Philippines says 299,404 sq km. I also very much doubt that Antarctica has exactly 14,000,000 sq km.

Is it somewhere said that it is exactly 14,000,000 sq km, and what is "exactly"? We do not know the precision of that figure. It may be 2 significant digits, but it may be ten, too.

I read in a Italian website that Philippines are exactly 300,000km2 but maybe it is a myth.

It doesn't, but since other continents show their areas to the last square kilometre, one could conclude that Antarctica does as well. And by "exactly 14,000,000 sq km" I mean between 13,999,999.5 and 14,000,000.4999... sq km.

Surface area of Antarctica changes yearly because of changing ice sheets (one year there are more, other less). 14 million sq. km is just an approximate number.

The Antarctic landmass don't change but it's difficult do distinguish where there's land below the ice sheet and where there's only water. This explains the approximation.

No, because ice is counted as well, otherwise Antarctica would be much smaller than 14M sq km.

Greenland is known as the largest island in the world while in reality is an archipelago covered by ice.

No, we cannot make that conclusion, for obvious reasons.

Better to say the the area is 14 million sq km. Then we know the precision, two significant digits, and anything between 13.5 and 14.5 million can be rounded to 14 milion.

I was browsing www.hadonejob.com and came across this pic:

I immediately recognized the location. Looked into the pics I made from my Berlin-trip (with school) and came across this. my pic was also taken near the Reichstag. Possibly the same intersection!

(almost the entire city of Berlin was a frikken construction zone when I was there . Still a very nice city though )

An average person doesn't know or doesn't think of those reasons. But most people would probably doubt about preciseness of that number anyway.

Trailing zeros of integers are not significant figures in terms of precision. Trust me.

Thus, 14000000 is not a more precise expression that 14 million if no information of the precision is provided. I have seen no credible reference showing 14.000000 million sq km as the area.

Basics:
