This function is used in Python Scripting.
Description​
Given two sequences of values, calculates the sum of each sequence and finds the difference between them. In other words, the difference between sums from two sets of numbers.
Throws a DimensionMismatchException if the two sequences have different lengths.

Syntax​
system.math.sumDifference(values1, values2)
Parameters​
| Type | Parameter | Description |
|---|---|---|
| List[Float] | values1 | A 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. |
| List[Float] | values2 | A 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. |
Returns​
Float - The sum difference, or NaN if one of the parameters was empty or null.
Scope​

Code Examples​
Example #1
# Create some lists.
firstList = [3.5, 5.6, 7.8, 7.4, 3.8]
secondList = [3.5, 5.6, -7.8, 7.4, -3.8]
# Print the resulting value.
print system.math.sumDifference(firstList, secondList)
