Understanding Common Boolean Operators
Here are the basic logic operations supported by the calculator.
AND Operator
The result is TRUE only if both inputs are TRUE.
| A | B | Result |
|---|---|---|
| TRUE | TRUE | TRUE |
| TRUE | FALSE | FALSE |
OR Operator
The result is TRUE if at least one input is TRUE.
| A | B | Result |
|---|---|---|
| TRUE | FALSE | TRUE |
| FALSE | FALSE | FALSE |
XOR Operator
The result is TRUE only if the inputs are different.
| A | B | Result |
|---|---|---|
| TRUE | FALSE | TRUE |
| TRUE | TRUE | FALSE |
NAND Operator
NAND is the opposite of AND.
It returns FALSE only when both inputs are TRUE.
NOR Operator
NOR is the opposite of OR.
It returns TRUE only when both inputs are FALSE.
NOT Operator
The NOT gate reverses the input value.
| Input | Output |
|---|---|
| TRUE | FALSE |
| FALSE | TRUE |
