Installation
Add this line to your application's Gemfile:
gem 'roman_nums'
And then execute:
$ bundle
Or install it yourself as:
$ gem install roman_nums
Usage
- Add your arabic_nums to a hash with
:arabic_nums
symbol key and numbers as an array for the value, then pass the arguments toRomanNums.convert(args)
like the example below. If you don't pass any args, and just runRomanNums.convert
it will return sample data for testing.
arabic_nums = [3994, 4336, 9233, 1376, 8851, 6222, 1839, 3570, 8660, 9018, 4448, 1827, 9753, 2738, 8386, 9867, 1698, 9022, 8631, 8382, 4752]
number_hashes = RomanNums.convert(arabic_nums: arabic_nums)
- Results as Array of Hashes:
