| - | + | ||
| - | If the calculation of the expression diverges, the corresponding table key is not inserted in the output table. So, when possible way to remove a key from a table is returning //null//. | + | |
| - | + | ||
| - | The list of mathematical and logical operators that can be employed in the logic/algebraic expression can be found in the [[Image Expression Type | image expression reference]]. Note that the operators and functions described in [[Image Expression Type#Image Operators and Functions | Image Operators and Functions]] and [[Image Expression Type#Image Neighborhood Functions | + | |
| - | | Image Neighborhood Functions]] can not be used in lookup table calculations. | + | |
| - | + | ||
| - | The tables used by the "Calculate Lookup Table" must be provided by a corresponding [[Number Table]] and the values must be provided by a corresponding [[Number Value]]. | + | |
