Thank you for reaching out to us.
Under the hood, the structure of real is:
boolean _isBlank;
int _hint;
long _value;When you set the value 5.0 with the MagnitudeType.EXPONENT_POS_1 (10^1) as a hint, the _value will be 0.5 which is not supported by long. I think it is converted to 1. Therefore, 1 * (10^1) is equal to 10.
When you set the value 4.9 with the MagnitudeType.EXPONENT_POS_1 (10^1) as a hint, the _value will be 0.49 which is not supported by long. I think it is converted to 0. Therefore, 0 * (10^1) is equal to 0.
You can try this one:
EmaFactory.createFieldEntry().realFromDouble(22, 5.0, OmmReal.MagnitudeType.EXPONENT_0); EmaFactory.createFieldEntry().realFromDouble(25, 4.9, OmmReal.MagnitudeType.EXPONENT_NEG_1);
The value I am trying to publish is getting round-off how can I resolve it?
below is the example of value I am passing and what it is getting published.
Value passed :-
nestedFieldList.add(EmaFactory.createFieldEntry().realFromDouble(22, 5.0, OmmReal.MagnitudeType.EXPONENT_POS_1));
nestedFieldList.add(EmaFactory.createFieldEntry().realFromDouble(25, 4.9, OmmReal.MagnitudeType.EXPONENT_POS_1));
Value received after publish :-
Fid: 22 Name = BID DataType: Real Value: 10.0
Fid: 25 Name = ASK DataType: Real Value: 0.0
Can anyone please let me know how I can resolve it?

Am getting below error when tried your suggestion
Exception in thread "pool-4-thread-1" Exception Type='OmmInvalidUsageException', Text='Passed in value is null', Error Code='-22'

Those code should not throw that exception.
Can you verify the call stack of that exception?

It relates to an ascii value.
What is in this line com.trep.publish.TrepPublishingClient.onRefreshMsg(TrepPublisher.java:98)?

nestedFieldList.add(EmaFactory.createFieldEntry().ascii(17, activ));

The activ may be null.
FieldList fieldList = EmaFactory.createFieldList();
String activ = null;
fieldList.add(EmaFactory.createFieldEntry().ascii(17, activ));The exception is:
Exception Type='OmmInvalidUsageException', Text='Passed in value is null', Error Code='-22'

Have removed the activ and tried with the EXPONENT_0 but it is also rounding off the values.
Can you please suggest any generic solution for all Double fields I am using as below?
nestedFieldList.add(EmaFactory.createFieldEntry().realFromDouble(22, getBid(), OmmReal.MagnitudeType.EXPONENT_0));

I Resolved it by passing numeric value.
Thanks for your time

If you want one decimal point, you can use the OmmReal.MagnitudeType.EXPONENT_NEG_1.
If you want two decimal points, you can use the OmmReal.MagnitudeType.EXPONENT_NEG_2.
