Logic operators
These are the fundamental tools to control flow in your functions.
- If (Z802): depending on whether the condition is true will return one or the other value
Basic Boolean operations
These are the basic blocks from which to build logic states.
- not (Z10216): takes a truth value and returns its opposite
- and (Z10174): Performs a Boolean and operation
- or (Z10184): Performs a Boolean OR operation
- Boolean equality (Z844): returns true only if both inputs are equal
- Boolean inequality (Z10237): returns true only if both inputs are different
