   My understanding agrees with @LakshSingla. It is an approximate algorithm that may return slightly different numbers. Nevertheless, all numbers returned by the algorithm fall within the expected error bounds. Like @LakshSingla mentioned you can raise `k` if you need tighter error bounds. It will improve accuracy, at the cost of using more memory and processing time.
