找到一些朋友他愿意帮你还是根你学习。 虽然这个看起来‘spam'一样（一定不是，我根'mandarin companion' 公司没有关）， 我一定建议念一些简单书。加油！ http://mandarincompanion.com/wp-content/uploads/samples/Mandarin%20Companion%20-%20Sherlock%20Holmes%20and%20the%20Red-Headed%20League%20%28Sample%29.pdf

It means 0.3% (rounded to one decimal place) or what we'd call "oh-point-three-recurring percent" or perhaps write as 0.3333333% or 0.3 with a dot on top of the 3 to indicate an infinite number of 3s. Your question should be "What percentage is this?". In the same way we ask "What quantity is X?" instead of 'how much qu..x--x--x'. The figure, 0.33%, is indeed slightly positive, though apparently it's *significantly/very positive* according to the context, and fair enough. Some systems have forces that serve to keep figures flat. Maybe even 0.1% would have been a lot for that year. Say a high-school of population 1000 students increases it's enrollment total by 0.3%. Well that's only 3 students - probably not much, but yes it all depends on context.
