Converting a given number to a word using array - ruby

Question

I am trying to create a method for the classic bottles of beers output.
Given a number, #beers, I want to convert it to the word version of the number. I wanted to split the number into an array and then compare with a list of numbers to words:
class BeerSong
attr_accessor :beers
def initialize(beers)
if beers > 99
beers = 99
elsif beers < 1
beers = "Zero"
end
#beers = beers
end
def worded
num_name = {
90 => "Ninety", 80 => "Eighty", 70 => "Seventy",60 => "Sixty",
50 => "Fifty",40 => "Forty",30 => "Thirty",20 => "Twenty",
19 => "Nineteen", 18 => "Eighteen", 17 => "Seventeen", 16 => "Sixteen",
15 => "Fifteen",14 => "Fourteen", 13 =>"Thirteen", 12 => "Twelve",
11 => "Eleven", 10 => "Ten", 9 => "Nine",8 => "Eight", 7 => "Seven",
6 => "Six",5 => "Five",4 => "Four",3 => "Three",2 => "Two",1 => "One"
}
worded = ""
beers = #beers
split_beers = beers.to_s.split
num_name.each do |number, name|
split_number = number.to_s.split
if beers == number
worded << name
else
number > 19 && split_number[0].to_i == split_beers[0].to_i
worded << name
worded << "-"
end
end
num_name.each do |number, name|
if number < 10 && split_beers[1].to_i == number
worded << name
end
end
worded
end
def print_song
while #beers.to_i > 2
puts "#{worded} bottles of beer on the wall,"
puts "#{worded} bottles of beer,"
puts "Take one down, pass it around,"
#beers -= 1
puts "#{worded} bottles of beer on the wall.\n\n"
end
if #beers.to_i == 2
puts "#{worded} bottles of beer on the wall,"
puts "#{worded} bottles of beer,"
puts "Take one down, pass it around,"
#beers -= 1
puts "#{worded} bottle of beer on the wall.\n\n"
end
if #beers.to_i == 1
puts "#{worded} bottle of beer on the wall,"
puts "#{worded} bottle of beer,"
puts "Take one down, pass it around,"
puts "Zero bottles of beer on the wall.\n\n"
end
if #beers.to_i == 0
print ""
end
end
end
I am trying to compare the first digit to get the tens, then compare the second digit for the units separated by a hyphen.

Answer 1

Your lines:
split_beers = beers.to_s.split
split_number = number.to_s.split
assume an array as a result which is not the case because you don't provide a pattern to split on
so the default is used. See: http://ruby-doc.org/core-2.0.0/String.html#method-i-split
puts "10".to_s.split.inspect # gives ==> ["10"]
puts "10".to_s.split('',2).inspect # gives ==> ["1", "0"]
The last is what you want.
