Any formats can mean positional/unary numeral systems :) So base number conversion under your choice.
- You can easily build base numbers.
- An example, upper the "36".
require 'integer/base'
Integer::Base.parse '10', %w[0 1 2 3 4 5 6 7 8 9] #=> 10
# Extend core methods with refinement
using Integer::Base
'10'.to_i %w[0 1] #=> 2
10.to_s %w[0 1] #=> "2"'10'.to_i 36 #=> 36
'10'.to_i [*'0'..'9', *'A'..'Z'] #=> 36
'10'.to_i 37 #=> ArgumentError
'10'.to_i [*'0'..'9', *'A'..'Z', '?'] #=> 37
'1?'.to_i [*'0'..'9', *'A'..'Z', '?'] #=> 73 (37 * 1 + 36 * 1)Actual usecase, special mapping as Crockford's base32
