>> "1,24,53,6,23,6,5".split(",").collect{ |s| s.to_i }
=> [1, 24, 53, 6, 23, 6, 5]
This is why Ruby is so fun to use. Is there a shorter way to do this than what I have?

Converts a comma separated string of numbers into an array of integers
This is all there is to convert a string of comma separated integers to an array of integers.
This is why Ruby is so fun to use. Is there a shorter way to do this than what I have?

possibly just doing %w(1,24,53,6,23,6,5)
%w(1,24,53,6,23,6,5) is the reverse of what I did.
>%w(1,24,53,6,23,6,5)
=> ["1,24,53,6,23,6,5"]
%w does not result in the ability to traverse through the array.
>> %w(1,24,53,6,23,6,5).length
=> 1
where
>>"1,24,53,6,23,6,5".split(",").collect{ |s| s.to_i }.length
=> 7
> %w(1,24,53,6,23,6,5) is the reverse of what I did.
The main problem with the first comment's example: %w() should use whitespaces rather than commas:
> %w(1 24 53 6 23 6 5)
=> ["1", "24", "53", "6", "23", "6", "5"]
Still, this returns Strings, so you can call map {|s| s.to} to get the same results..
not sure this is relevant though..
"1,24,53,6,23,6,5".split(",").map(&:to_i)
