Moved <20 check to tens method
tens now has a val parameter
cleared zero value from ONES array
tens method done
hundreds method done
built up array of three digit values and reverse_each-ed it
small typos, added test for last digitgroup to avoid hundreds to be at the end when unnecessary.
corrected hundreds method. If the group ends with 00, now it will end the numeral correctly omitting the 'and'.
Comment added.
