Notes
The list of mathematical and logical operators that can be employed in the logic/algebraic expression can be found in the image expression reference. Note that the operators and functions described in Image Operators and Functions and Image Neighborhood Functions can not be used in value calculations.
The tables used by the “Calculate Value” must be provided by a corresponding Number Table and the values must be provided by a corresponding Number Value.
For additional information about how the null values are handled during image and value calculation, see this reference.
