I read that range of BLEU is 0 to 1.(from "BLEU" page on wikipedia)

But i found some paper says like

"we achieve a significant gain of 5.0 BLEU points over non-attentional systems that already incorporate known techniques such as dropout"

Does "5.0 BLEU points" mean 0.5 BLEU?
or BLEU range is not 0 to 1 and actually exceed 1?

The BLEU score is between 0 and 1, but is sometime expressed as a percentage, i.e. ranging from 0 to 100%.

E.g. http://www.statmt.org/moses/?n=Moses.SupportTools#ntoc5 returns a score between 0 and 100 (code).
