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)
# File json/lib/json/add/rational.rb, line 29 def as_json(*) { JSON.create_id => self.class.name, 'n' => numerator, 'd' => denominator, } end
to_json(*args)

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