in WebSocket API

I query RIC code TUU0, field SETTLE using websocket connection to TREP machine. it return me a number 110.4219, however the RIC page from desktop application Eikon show 100 108/256 = 110.421875, why websocket truncate to 4th digit. Seems wrong!


This automatically truncating does not happen in getting option settlement price.

    I have connected to ADS3.4.0.L1 with the WebSocket connection.

    The retrieved price wasn't truncated. 

    RECEIVED:
    [
      {
        "Fields":{
          "ACTIV_DATE":"2020-07-17",
    ... 
          "ACVOLTM_MS":"08:15:34.167",
          "ACVOL_1":15569,
          "ACVOL_TIM":"08:15:34",
    ...
          "SETTLE":110.421875,
          "SETTLEDATE":"2020-07-16",
          "SETTLE_TIM":"23:34:56",
    ...
        },
        "ID":2,
        "Key":{
          "Name":"TUU0",
          "Service":"ELEKTRON_REPLABLINUX1"
        },
        "PermData":"AxHvMVPA",
        "Qos":{
          "Rate":"TickByTick",
          "Timeliness":"Realtime"
        },
        "SeqNumber":33472,
        "State":{
          "Data":"Ok",
          "Stream":"Open",
          "Text":"All is well"
        },
        "Type":"Refresh"
      }
    ]

    It looks like to be a bug fixed in ads3.4.0.L1.


    TREP-2667; WebSocket price fields are rounded to 4 decimal places.
    Case 08218129
        RWF to JSON converter library (librsslJsonConverter.so.1) has loss of precision for REAL fields if
        greater than 4 decimal places.
