> Converting to engineering notation occurs only when buffering has been configured in the rewrite rules. It's related to usage of BigDecimal.stripTrailingZeros() in the com.fasterxml.jackson.databind.node.JsonNodeFactory.numberNode(BigDecimal v) by default.
> For example, original JSON
> {code}
> {
> 	"apps":{
> 		"app":[
> 			{
> 				"id":"one",
> 				"progress":100.0,
> 				"startedTime":1399975176760
> 			}
> 		]
> 	}
> }
> {code}
> Rewritten JSON
> {code}
> {
> 	"apps":{
> 		"app":[
> 			{
> 				"id":"one",
> 				"progress":1E+2,
> 				"startedTime":1.39997517676E+12
> 			}
> 		]
> 	}
> }
> {code}
