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

#to_json(*args) ⇒ Object
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"}
