We are loading the data from hive environment to qlikview qvds. we are not having any datatype in the Qlikview datamodel. Now please let me know what will be the default Precision and scale in the Qlikview if I load a decimal data from HIVE into Qlikview column.
There's only one numeric data type in Qlikview and it's the IEEE 754 Floating point. Using the num() function and the Number formatting options in chart objects you can change the displayed scale and precision, but the actual numeric value will still be the same. Formatting doesn't change a numeric value. Rounding does. So if you use the Round(), Floor() or Ceil() functions you do change the value. Perhaps this blog post helps: Rounding Errors
