I am using Logstash 1.5.5, Kafka as input using JSON codec, a structured message is received by Logstash:  
{  
"app\_id" ": "myapp"  
......  
"log\_message": {  
"id": "1234",  
"code": "whatever",  
"amount": 284.84  
}  
}

I am converting log\_message to String using JSON.dump like this:  
string\_message = JSON.dump event["log\_message"];

string\_message obtained value is {"id": "1234", "code": "whatever","amount": "0.28484E3"}

There is a way to avoid this transformation to scientific format of BigDecimal into string\_message? I need to preserve amount value as 284.84

that log\_message JSON message value is variable as structure, decimal values could be present on several message levels with variable attribute name.

There is a way to have a global setting about what decimal format should be used?
