ComfyUI Node: LogicUtil_Bitwise Shift

LogicUtil_Bitwise Shift:

The LogicUtil_LogicGateBitwiseShift node is designed to perform bitwise shift operations on integer values. This node allows you to shift the bits of an integer (input1) by a specified number of positions (input2). A positive input2 value shifts the bits to the left, effectively multiplying the number by a power of two, while a negative input2 value shifts the bits to the right, effectively dividing the number by a power of two. This operation is particularly useful in scenarios where you need to perform efficient mathematical operations or manipulate binary data at a low level. The node ensures that the shift amount is within a valid range to prevent errors.

LogicUtil_Bitwise Shift Input Parameters:

input1

input1 is the integer value whose bits you want to shift. This parameter serves as the base number for the bitwise shift operation. The default value is 0, and it must be an integer. The value of input1 determines the initial binary representation that will be shifted.

input2

input2 specifies the number of bit positions to shift input1. A positive value shifts the bits to the left, while a negative value shifts the bits to the right. The default value is 0, and it must be an integer. The valid range for input2 is between -32 and 32, inclusive. This range ensures that the shift operation remains within the bounds of typical integer sizes.

LogicUtil_Bitwise Shift Output Parameters:

INT

The output is a single integer value resulting from the bitwise shift operation. This value represents the new integer obtained after shifting the bits of input1 by the number of positions specified in input2. The output is crucial for applications requiring precise control over binary data manipulation or efficient mathematical computations.

LogicUtil_Bitwise Shift Usage Tips:

• Ensure that input2 is within the range of -32 to 32 to avoid errors and ensure valid shift operations.
• Use positive values for input2 to perform left shifts (multiplication by powers of two) and negative values for right shifts (division by powers of two).
• This node is particularly useful for low-level data manipulation tasks, such as encoding, decoding, or optimizing mathematical operations.

LogicUtil_Bitwise Shift Common Errors and Solutions:

ValueError: input2 must be between -32 and 32

• Explanation: This error occurs when the value of input2 is outside the valid range of -32 to 32. - Solution: Ensure that the value of input2 is within the specified range. Adjust the value accordingly to fall between -32 and 32.

TypeError: input1 and input2 must be integers

• Explanation: This error occurs when either input1 or input2 is not an integer.
• Solution: Verify that both input1 and input2 are provided as integer values. Convert any non-integer inputs to integers before using the node.
