Dear Diego,

you could easily adapt the C code given on the Wikipedia page.
Ruby supports bit-level operations on numbers, and the operator symbols for those operations are the same as in C ...
or you could use ffi (http://blog.headius.com/2008/10/ffi-for-ruby-now-available.html) to use Ruby to wrap the C code given there right away.

Best regards,

Axel
