We have just switched from RFA/MarketlinkIP to EMA/Contributions Channel and when contributing to 2 decimal places of precision we are now seeing 4 decimal places shown on Elektron. Can we restrict the precision back to 2 decimal places?

    Hi @peter.morris

    Can you please confirm which version of EMA you are using and the language version too?

    I just tried the following values with a recent EMA Java version (EMA Java 3.6.0)

    and if I post the following values to a RCC test RIC:

    int _bid = 3400, _ask = 3410;

    using:

    FieldList nestedFieldList = EmaFactory.createFieldList();
    nestedFieldList.add(EmaFactory.createFieldEntry().real(22, _bid++, OmmReal.MagnitudeType.EXPONENT_NEG_2));
    nestedFieldList.add(EmaFactory.createFieldEntry().real(25, _ask++, OmmReal.MagnitudeType.EXPONENT_NEG_2));

    I see the following:

    If, however, I use int _bid = 340000, _ask = 341000 and EXPONENT_NEG_4, I see the following:

    I have not tested with EMA C++, but I expect the same behaviour will manifest.

    I viewed the above values in both Refinitiv workspace and a RFA Java Gui example.
