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
# File json/lib/json/add/bigdecimal.rb, line 35 def as_json(*) { JSON.create_id => self.class.name, 'b' => _dump, } end
to_json(*args)
click to toggle source
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"}
