  Ninety-eight and a half bottles of beer on the wall.
HERE

number_scanner.scan # => [99, 99, 1, (197/2)]

puts number_scanner.scrub { |n| "<span data-n='#{n.value.to_f}'>#{n}</span>" }
<span data-n='99.0'>Ninety-nine</span> bottles of beer on the wall.
<span data-n='99.0'>Ninety-nine</span> bottles of beer.
