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:

Example

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:

Example

Rational.json_create(x)
# => (2/3)
