array	The array of values.
k	The percentile value in the range 0..1 (inclusive).

REMARKS

* PERCENTILE.INC was added in Excel 2010 to replace this function.
* For an illustrated example refer to the page under Advanced Functions
* If "array" is empty or contains more than 8,191 data points, then #NUM! is returned.
* If "k" < 0, then #NUM! is returned.
* If "k" > 1, then #NUM! is returned.
* If "k" is not numeric, then #VALUE! is returned.
* If "k" is not a multiple of 1/(n - 1), then this function interpolates to determine the value at the kth percentile.
* You can use the PERCENTILE.EXC function to return the number corresponding to a particular percentage from an array of numbers (exclusive).
* You can use the QUARTILE.INC function to return the fixed percentiles of 0, 25, 50, 75 and 100.
