Methods Rational#as_json
and Rational.json_create
may be used to serialize and deserialize a Rational object; see Marshal.
Method Rational#as_json
serializes self
, returning a 2-element hash representing self
:
require 'json/add/rational'
x = Rational(2, 3).as_json
# => {"json_class"=>"Rational", "n"=>2, "d"=>3}
Method JSON.create
deserializes such a hash, returning a Rational object:
Rational.json_create(x)
# => (2/3)

#to_json(*args) ⇒ Object
Returns a JSON string representing self
:
require 'json/add/rational'
puts Rational(2, 3).to_json
Output:
{"json_class":"Rational","n":2,"d":3}
