Methods BigDecimal#as_json and BigDecimal.json_create may be used to serialize and deserialize a BigDecimal object; see Marshal.

Method BigDecimal#as_json serializes self, returning a 2-element hash representing self:

require 'json/add/bigdecimal'
x = BigDecimal(2).as_json             # => {"json_class"=>"BigDecimal", "b"=>"27:0.2e1"}
y = BigDecimal(2.0, 4).as_json        # => {"json_class"=>"BigDecimal", "b"=>"36:0.2e1"}
z = BigDecimal(Complex(2, 0)).as_json # => {"json_class"=>"BigDecimal", "b"=>"27:0.2e1"}

Method JSON.create deserializes such a hash, returning a BigDecimal object:

BigDecimal.json_create(x) # => 0.2e1
BigDecimal.json_create(y) # => 0.2e1
BigDecimal.json_create(z) # => 0.2e1

Returns a JSON string representing self:

require 'json/add/bigdecimal'
puts BigDecimal(2).to_json
puts BigDecimal(2.0, 4).to_json
puts BigDecimal(Complex(2, 0)).to_json

Output:

{"json_class":"BigDecimal","b":"27:0.2e1"}
{"json_class":"BigDecimal","b":"36:0.2e1"}
{"json_class":"BigDecimal","b":"27:0.2e1"}

Method JSON.create deserializes such a hash, returning a OpenStruct object:

OpenStruct.json_create(x)
# => #<OpenStruct name='Rowdy', age=nil>

z = ('a'..'d').as_json # => {"json_class"=>"Range", "a"=>["a", "d", false]}

Method JSON.create deserializes such a hash, returning a Range object:

Range.json_create(x) # => 1..4

Calls the given block with each member name/value pair; returns self:

Customer = Struct.new(:name, :address, :zip) # => Customer
joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
joe.each_pair {|(name, value)| p "#{name} => #{value}" }

Output:
