Fractile() finds the value that corresponds to the inclusive fractile (quantile) of the aggregated data in the expression over a number of records as defined by a group by clause.
Return data type: numeric
The function returns the value corresponding to the rank as defined by rank = fraction * (N-1) + 1 where N is the number of values in expr. If rank is a non-integer number, an interpolation is made between the two closest values.
|expr||The expression or field containing the data to use when calculating the fractile.|
|fraction||A number between 0 and 1 corresponding to the fractile (quantile expressed as a fraction) to be calculated.|
