integer-base¶ ↑

• github.com/kachick/integer-base

• rubygems.org/gems/integer-base

• rubyforge.org/projects/integer-base

Description¶ ↑

Your format comes into positional numeral systems.

Feautures¶ ↑

• You can build upper 36 basenumbers so easily

• And get own formats so easily too :)

  e.g.

  • 0 1 -> 0 a

  • 0 1 2 3 4 5 6 7 8 9 -> a b c d e f g h i j

Usage¶ ↑

• Setup

  require 'integer/base'
  

• Basic

  Integer::Base.parse '10', %w[0 1]   #=> 2
  

• Extend Ruby’s Interface

  require 'integer/base/ext'
  

• to_i

  'a'.to_i   ['0', *'A'..'I']        #=> 1
  'a0'.to_i  ['0', *'A'..'I']        #=> 10
  'aib'.to_i ['0', *'A'..'I']        #=> 192
  

• to_s

  192.to_s   ['0', *'A'..'I']        #=> 'aib'
  

• Already defined useful chars

  '10'.to_i Integer::Base::STANDARD_CHARS[36].last         #=> :Z
  '10'.to_i Integer::Base::STANDARD_CHARS[:BINARY].last    #=> :"1"
  

• Get own formats

  'a'.to_i  %w[0 a]                  #=> 1
  'a0'.to_i %w[0 a]                  #=> 2
  

• Upper 36 basenumbers

  '1!'.to_i([*Integer::Base::STANDARD_CHARS[36], '!']) #=> 73
