This is not quite "my module", but one that I have participated somewhat. As of version 0.01 it gets a mere 3 rating, as the
documentation could use quite some shape-up.
It is quite easy to use, but in fact is intended to serve as low-level module to the Lingua::Num2Word container.
Version 0.02 offers some bugfixes (for 16,17 and x00) and some
code clean-up and thus deserves 4 stars.
