keywords	bit, operation, negation, boolean

Purpose

The module BoolArithmetic computes simple boolean operations.

Usage

Select the desired operation and mark the boolean input fields.

Details

Depending on the given input values, corresponding boolean output values are being computed.

The following table gives an overview over the given boolean operations:

Operation	Input Bool A	Input Bool B	Output Bool C
Identity	A	–	A
Negation	A	–	-A
And	A	B	A and B
Or	A	B	A or B
Xor	A	B	A xor B
Equal	A	B	A == B
Implication	A	B	A –> B

Bool B: Bool

Bool C: Bool

Changed to false: []: Trigger

Changed to true: []: Trigger

Int. Value: Integer

Operation: Enum

Visible Fields

Bool A

name: inputBool1, type: Bool, default: FALSE

Sets the first input boolean value.

Bool B

name: inputBool2, type: Bool, default: FALSE

Sets the second input boolean value.

Bool C

name: outputBool, type: Bool, persistent: no

Shows the result of the boolean operation.

Bool !C

name: negatedOutputBool, type: Bool, persistent: no

Shows the inverse of the result of the boolean operation.

Int. Value

name: outputInt, type: Integer, persistent: no

Shows the result of the boolean operation as an integer.

0 means false and 1 means true.

Operation

name: operation, type: Enum, default: Identity

Defines the boolean operation applied to Bool A (and optionally Bool B).

Values:

Title	Name
​Identity	​Identity
​Negation	​Negation
​And	​And
​Or	​Or
​Xor	​Xor
​Equal	​Equal
​Implication	​Implication

Changed to true: []

name: outputChangedToTrue, type: Trigger, persistent: no

This field is touched when the output value changes from false to true. You can connect this to other notifications fields.

Changed to false: []

name: outputChangedToFalse, type: Trigger, persistent: no

This field is touched when the output value changes from true to false. You can connect this to other notifications fields.
