/**
 * Returns the value at which a certain percentage of observed values occur. For example, the 95th percentile is the value which is greater than 95% of the observed values and the 50th percentile is the `MEDIAN`.
 *
 * @example
 * FROM employees
 * | STATS p0 = PERCENTILE(salary,  0)
 *      , p50 = PERCENTILE(salary, 50)
 *      , p99 = PERCENTILE(salary, 99)
 *
 * @example
 * FROM employees
 * | STATS p80_max_salary_change = PERCENTILE(MV_MAX(salary_change), 80)
 *
 * @example
 * TS exp_histo_sample
 * | WHERE instance == "instance-0"
 * | STATS p99 = ROUND(PERCENTILE(responseTime, 99), 4)
 *
 * @example
 * TS histogram_timeseries_index
 * | WHERE instance == "instance-0"
 * | STATS p95 = ROUND(PERCENTILE(responseTime::tdigest, 95), 2)
