This function is used in Python Scripting.


Given a sequence of numerical values, estimates the percentile of input.

The percentile is a value on a scale that represents a percentage position in a list of data that can be equal to or below that value: i.e., the 25th percentile is a value below which 25% of observable data points may be found.

Client Permission Restrictions

This scripting function has no Client Permission restrictions.


system.math.percentile(values, percentile)


List[Float]valuesA sequence of numerical values. Accepts both integers and floats. The sequence may not contain None type values. However, passing a None type object instead of a sequence of numerical values will return NaN.
FloatpercentileThe percentile to compute. A float greater than 0 and less than or equal to 100. Will throw an exception if the percentile is out of bounds.


Float - A value from the given list using the requested percentile of the input, or NaN if the input was empty or null.
