Methods Complex#as_json and Complex.json_create may be used to serialize and deserialize a Complex object; see Marshal.
Method Complex#as_json serializes self, returning a 2-element hash representing self:
Example
require 'json/add/complex' x = Complex(2).as_json # => {"json_class"=>"Complex", "r"=>2, "i"=>0} y = Complex(2.0, 4).as_json # => {"json_class"=>"Complex", "r"=>2.0, "i"=>4}
Method JSON.create deserializes such a hash, returning a Complex object:
Example
Complex.json_create(x) # => (2+0i) Complex.json_create(y) # => (2.0+4i)
