# Methods <tt>BigDecimal#as_json</tt> and +BigDecimal.json_create+ may be used
# to serialize and deserialize a \BigDecimal object;

#
# \Method <tt>BigDecimal#as_json</tt> 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
