Operator Reference
tuple_median (Operator)
tuple_median — Return the median of the elements of a tuple.
Signature
Description
tuple_median calculates the median of all elements of the
input tuple Tuple and returns it in the output parameter
Median. The input tuple may only consist of numbers
(integer or floating point numbers). The median is defined as the
element with rank n/2 (see tuple_select_rank).
Note that for an even number of input elements, this will return the upper
median, not the arithmetic median. To calculate the arithmetic median, you
can use tuple_select_rank to select the upper and lower median values
and then calculate the arithmetic mean of both values.
Exception: Empty input tuple
If the input tuple is empty, an exception is raised.
HDevelop In-line Operation
