The value I am trying to publish is getting round-off how can I resolve it?

nsharma

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?

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);
