  (2)  If the P argument to percentile(Y,P) is not the same for every
       row in the aggregate then an error is thrown.  The word "same"
       in the previous sentence means that the value differ by less
       than 0.001.
  (3)  If the P argument to percentile(Y,P) evaluates to anything other
       than a number in the range of 0.0 to 100.0 inclusive then an
       error is thrown.
  (4)  If any Y argument to percentile(Y,P) evaluates to a value that
       is not NULL and is not numeric then an error is thrown.
  (5)  If any Y argument to percentile(Y,P) evaluates to plus or minus
       infinity then an error is thrown.  (SQLite always interprets NaN
       values as NULL.)
  (6)  Both Y and P in percentile(Y,P) can be arbitrary expressions,
       including CASE WHEN expressions.
  (7)  The percentile(Y,P) aggregate is able to handle inputs of at least
       one million (1,000,000) rows.
  (8)  If there are no non-NULL values for Y, then percentile(Y,P)
       returns NULL.
  (9)  If there is exactly one non-NULL value for Y, the percentile(Y,P)
       returns the one Y value.
 (10)  If there N non-NULL values of Y where N is two or more and
