New maintainers never bothered to change the range.. History num2words is based on an old library, pynum2word, created by Taro Ogawa in 2003. Unfortunately, the library stopped being maintained and the author can't be reached. There was another developer, Marius Grigaitis, who in 2011 added Lithuanian support, but didn't take over maintenance of the project.

I am thus basing myself on Marius Grigaitis' improvements and re-publishing pynum2word as num2words.
