> Calcite currently has implementations for the {{PERCENTILE_CONT}} and {{PERCENTILE_DISC}} functions. Their syntax may be found [here|https://learn.microsoft.com/en-us/sql/t-sql/functions/percentile-cont-transact-sql?view=sql-server-ver16]. 
> BigQuery offers these functions as well, but the syntax is slightly different, and may be found [here|https://cloud.google.com/bigquery/docs/reference/standard-sql/functions-and-operators#percentile_cont]. The main difference is that instead of using a {{WITHIN GROUP}} clause, the array is passed in directly as the first argument to the function.
