If the index i is an integer, the pS1U1P1thS1S1P0 percentile is the average of the data values in positions i and i+1. This is because the pS1U1P1thS1S1P0 percentile is the point in the data set where pS1U1P1% of the data falls below that point. If i is an integer, then pS1U1P1% of the data falls below the data value in position i, and (100-pS1U1P1)% of the data falls above that value. So, we need to find the data values in positions i and i+1 that bracket the point where 100-pS1U1P1% of the data falls above that value. The average of these data values is the pS1U1P1thS1S1P0 percentile.
