Remarks

If column is empty, BLANK() is returned.

If k is zero or blank, percentile rank of 1/(n+1) returns the smallest value. If zero, it is out of range and an error is returned.

If k is nonnumeric or outside the range 0 to 1, an error is returned.

If k is not a multiple of 1/(n + 1), PERCENTILE.EXC will interpolate to determine the value at the k-th percentile.

PERCENTILE.EXC will interpolate when the value for the specified percentile is between two values in the array. If it cannot interpolate for the k percentile specified, an error is returned.
