Calculates the signed area of a simple polygon.
X-coordinates of the vertices of the polygon. You must specify at least three elements in this input.
Y-coordinates of the vertices of the polygon. You must specify the same number of elements in y and x.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Signed area of the polygon. signed area is positive if the vertices of the polygon are in counterclockwise order. Otherwise, signed area is negative.
Error information.
The node produces this output according to standard error behavior.

A simple polygon is a polygon with no boundaries that cross each other.
The following equation defines the signed area of a simple polygon.
