Naive Inaccurate to_roman

to_roman.rb

# Doubt 100% accurate answer, but seems somewhat correct.

TRANSLATOR = {
  1000 => 'M',
  900 => 'CM',
  500 => 'D',
  400 => 'CD',
  100 => 'C',
  90 => 'XC',
  50 => 'L',
  40 => 'XL',
  10 => 'X',
  9 => 'IX',
  5 => 'V',
  4 => 'IV',
  1 => 'I',
}

def to_roman(number)
  result = ''

  # Iterate through the translator, assuming we are in an ordered hash (ruby 1.9+)
  # Order is important, must start with largest value and work down to lowest value
  TRANSLATOR.each do |arabic_value, roman_numeral|
    divisor = number / arabic_value
    result += roman_numeral * divisor
    # next iteration should set the number to the remainder
    number = number % arabic_value
  end

  return result
end


#Simple Test:
(1..3999).each do |num|
  puts "#{num} as a roman numeral: #{to_roman(num)}"
end
