Unable to publish exact double value using ETA3.8.3.0

Hi,

Asking this question on behalf of my developer colleague (I'm not a developer myself):

When trying to publish double value to trep, for example: 4324.920024907418

the result seen in the consuming app is 4324,920024907419 or other sligthly different value, probably affected by rounding.

We have tried different approaches but we're unable to get the exact same number as the one we publish.

Any suggestions as to how to get around this and get exact same values?

Example 1:

===============================

    // private final Real doubleValue      = CodecFactory.createReal();
    doubleValue.clear();
    System.out.println("Value before: ");
    System.out.println(value);
    doubleValue.value(value,
            RealHints.EXPONENT_12
    );
    System.out.println("tostring after");
    System.out.println(doubleValue.toString());
    System.out.println("todouble after");
    System.out.println(doubleValue.toDouble());

-----

Value before: 
4324.920024907418
tostring after
4324,920024907419
todouble after
4324.920024907419

Consumer app sees value
4324,920024907419

Example 2:

===============================

    // private final Real doubleValue      = CodecFactory.createReal();
    doubleValue.clear();
    System.out.println("Value before: ");
    System.out.println(value);
    doubleValue.value(value,
            RealHints.EXPONENT_11
    );
    System.out.println("tostring after");
    System.out.println(doubleValue.toString());
    System.out.println("todouble after");
    System.out.println(doubleValue.toDouble());
