Split an Integer into an Array

I needed this for implementing a arabic to roman numeral converter. I needed to split the integer into an array of its digits.

digit = 123
digits = digit.to_s.chars.map(&:to_i)

puts digits.inspect

And if you want to reverse the array, you can use the reverse method.

digit = 123
digits = digit.to_s.chars.reverse.map(&:to_i)

puts digits.inspect
