* Click on the function's arguments above for more details on the input values.

  • The column needs to be an attribute with numerical values in the model.
  • The math operations are not running on measures (aka 'values' or 'metrics'). They are operating on atomic items in the attribute / column itself. These values can then be subsequently used to drive an aggregated metric.

Different Function types
  • This function is similar to the PQL semantic and common functions of the same name. However, it operates on a column directly at the grain.
  • As a granular function, it is used in the base SQL query itself.
