Module: Radix

Defined in:
lib/radix/base.rb,
lib/radix/number.rb,
lib/radix/meta/data.rb

Overview

Radix coverts to and from any base.

Base conversions with ASCII ordered notations are easy in Ruby.

255.to_s(16)   #=> "FF"
"FF".to_i(16)  #=> 255

But Ruby reaches it’s limit at base 36.

255.to_s(37)   #=> Error

Radix provides the means of converting to and from any base.

Radix::Base.convert_base([100, 10], 256, 10)
#=> [2,5,6,1,0]

And it can handle any notation upto base 62.

Radix::Base.convert("10", 62, 10)  #=> "62"

And the notations need not be in ASCII order –odd notations can be used.

b10 = Radix::Base.new([:Q, :W, :E, :R, :T, :Y, :U, :I, :O, :U])
b10.convert("FF", 16) #=> "EYY"
