Owning Palette: Arithmetic & Comparison Express VIs
Requires: Base Development System. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Express Boolean functions to perform logical operations on Boolean values.
| Palette Object | Description |
|---|---|
| And | Computes the logical AND of the inputs. Both inputs must be Boolean values, numeric values, or error clusters. If both inputs are TRUE, the function returns TRUE. Otherwise, it returns FALSE. |
| Exclusive Or | Computes the logical exclusive or (XOR) of the inputs. Both inputs must be Boolean values, numeric values, or error clusters. If both inputs are TRUE or both inputs are FALSE, the function returns FALSE. Otherwise, it returns TRUE. |
| False Constant | Use this constant to provide a value of FALSE to the block diagram. |
| Implies | Negates x and then computes the logical OR of y and the negated x. Both inputs must be Boolean values, numeric values, or error clusters. If x is TRUE and y is FALSE, the function returns FALSE. Otherwise, it returns TRUE. |
| Not | Computes the logical negation of the input. If x is FALSE, the function returns TRUE. If x is TRUE, the function returns FALSE. |
| Not And | Computes the logical NAND of the inputs. Both inputs must be Boolean values, numeric values, or error clusters. If both inputs are TRUE, the function returns FALSE. Otherwise, it returns TRUE. |
| Not Exclusive Or | Computes the logical negation of the logical exclusive or (XOR) of the inputs. Both inputs must be Boolean values, numeric values, or error clusters. If both inputs are TRUE or both inputs are FALSE, the function returns TRUE. Otherwise, it returns FALSE. |
| Not Or | Computes the logical NOR of the inputs. Both inputs must be Boolean values, numeric values, or error clusters. If both inputs are FALSE, the function returns TRUE. Otherwise, it returns FALSE. |
| Or | Computes the logical OR of the inputs. Both inputs must be Boolean values, numeric values, or error clusters. If both inputs are FALSE, the function returns FALSE. Otherwise, it returns TRUE. |
| True Constant | Use this constant to provide a value of TRUE to the block diagram. |
