BigDecimal + as_json() = String?

Question

Ruby on Rails

Hello. It's best to do it in as_json() with BigDecimal in String.
and then I get the following result

{"count_plan"=>#BigDecimal:a639408,'0.2E1',9(18)}

Thanks

This is the case when pretty-printing objects in Ruby, useful for debugging.
And to serialize to JSON, a string should be used myobj.to_json.

h = {b: BigDecimal.new('12.34'), s: 'string'}
puts h.to_json

Shows
{"b":"12.34","s":"string"}
Apparently, the name as_json is confusing, because people think that the output will be a string in JSON format. And this is not so.
