ComfyUI Node: LogicUtil_Bitwise Not

LogicUtil_Bitwise Not:

The LogicUtil_LogicGateBitwiseNot node performs a bitwise NOT operation on a given integer input. This operation inverts each bit of the input number, turning all 1s to 0s and all 0s to 1s. This node is particularly useful in scenarios where you need to manipulate binary data or perform low-level bitwise operations. By providing a simple and efficient way to invert the bits of an integer, this node can be a valuable tool in various logical and computational tasks.

LogicUtil_Bitwise Not Input Parameters:

input1

input1 is the integer value on which the bitwise NOT operation will be performed. This parameter is essential as it determines the input number whose bits will be inverted. The default value for input1 is 0, but you can provide any integer value to see its bitwise NOT result. The bitwise NOT operation will flip each bit of the provided integer, producing a new integer as the output.

LogicUtil_Bitwise Not Output Parameters:

INT

The output is an integer that represents the result of the bitwise NOT operation on the input integer. This output is crucial as it provides the inverted bit representation of the input number. For example, if the input integer is 5 (which is 00000101 in binary), the output will be -6 (which is 11111010 in binary, considering two's complement representation for negative numbers).

LogicUtil_Bitwise Not Usage Tips:

• Use this node when you need to invert the bits of an integer for tasks such as binary data manipulation or low-level programming.
• Ensure that the input value is an integer, as the node only works with integer inputs.

LogicUtil_Bitwise Not Common Errors and Solutions:

Invalid input type

• Explanation: The input provided is not an integer.
• Solution: Ensure that the input1 parameter is an integer value. If you are passing a variable, make sure it is correctly cast to an integer before using this node.

Unexpected output value

• Explanation: The output value is not as expected due to misunderstanding of the bitwise NOT operation.
• Solution: Remember that the bitwise NOT operation inverts each bit of the input integer. For positive integers, this will result in a negative number due to the two's complement representation. Double-check your input and understand the binary representation to predict the correct output.
