----------------------------------------

             Summary: JacksonUtils is not symmetric
                 Key: AVRO-3876
                 URL: https://issues.apache.org/jira/browse/AVRO-3876
             Project: Apache Avro
          Issue Type: Bug
            Reporter: Christophe Le Saec
            Assignee: Christophe Le Saec


For each json node, you should have
{code:java}
Object object = JacksonUtils.toObject(node);
JsonNode node1 = JacksonUtils.toJsonNode(object);
Assertions.assertEquals(node, node1);
{code}

But, that's not true for
{code:java}
JsonNodeFactory.instance.numberNode(33.33000183105469f);
{code}
where test give
{noformat}
org.opentest4j.AssertionFailedError: 
Expected :33.33
Actual   :33.33000183105469
{noformat}
because toObject method transform float to double and by default, Float.toString method gives round values, as this code
{code:java}
    float x = 33.33000183105469f;
    System.out.println("value float  = " + x);
    System.out.println("value double = " + (double) x);
{code}
shows
{noformat}
value float  = 33.33
value double = 33.33000183105469
{noformat}
