in ETA

We are upgrading our application to use ETA API for Shanghai International Energy Exchange. Most of the symbols for this exchange publish incorrect TURNOVER (FID#100) with an extra digit. For example, ILUH3 on Nov 2 10:55AM shows:

</UPDATE>

Both RFA and Eikon display this figure as 3898134. Refinitiv customer support advise me to post this query here so that Refinitiv developers can investigate the issue.

    @HermesT

    It means that the data is 3898134.0.

    How does the client decode it to 38981340?

    If the client gets it directly from RsslInt value, it is definitely 38981340. 

    typedef struct
    {
        RsslBool        isBlank;    /*!< @brief RSSL_TRUE if this real value is blank  */
        RsslUInt8        hint;        /*!< @brief Populated with an enumerated value from \ref RsslRealHints */
        RsslInt            value;        /*!< @brief raw signed value with decimal point or denominator removed and accounted for in the RsslReal::hint */
    } RsslReal;

    The client must apply hint to the value before using it.

    Sorry about the issue that you are facing.

    The field 100 is RsslReal so its structure is :

    typedef struct
    {
        RsslBool        isBlank;    /*!< @brief RSSL_TRUE if this real value is blank  */
        RsslUInt8        hint;        /*!< @brief Populated with an enumerated value from \ref RsslRealHints */
        RsslInt            value;        /*!< @brief raw signed value with decimal point or denominator removed and accounted for in the RsslReal::hint */
    } RsslReal;

    RsslReal contains a hint and 0D is RSSL_RH_EXPONENT_1. Therefore, 38981340 * (10^-1) = 3898134.0.

    "0D02 52CE DC" represents "3898134.0".

    The client can use the rsslRealToDouble or rsslRealToString method in ETA to convert a RsslReal to a double or string, respectively.

    Jirapongse. Does it mean converting from Real to long is incorrect?
