ComfyUI Node: Float Math

Float Math:

The SeargeFloatMath node is designed to perform a variety of mathematical operations on floating-point numbers, making it a versatile tool for AI artists who need to manipulate numerical values within their workflows. This node allows you to choose from several predefined operations, such as multiplication, addition, subtraction, and division, and apply them to input values. By providing a flexible and straightforward way to perform these calculations, the SeargeFloatMath node helps streamline processes that require mathematical adjustments, ensuring that you can achieve precise and accurate results with minimal effort.

Float Math Input Parameters:

op

The op parameter specifies the mathematical operation to be performed. You can choose from the following options: a * b + c, a + c, ``a

• c, a * b, and a / b. The default operation is a * b + c``. This parameter determines how the input values a, b, and c will be combined to produce the result.

a

The a parameter is a floating-point number that serves as one of the primary inputs for the selected mathematical operation. It has a default value of 0.0 and can be adjusted in increments of 0.01. This value plays a crucial role in the calculation, especially in operations involving multiplication or addition.

b

The b parameter is another floating-point number used in the mathematical operation. It has a default value of 1.0 and can be adjusted in increments of 0.01. This parameter is particularly important for operations that involve multiplication or division, as it directly influences the scaling of the result.

c

The c parameter is a floating-point number that acts as an additional input for the mathematical operation. It has a default value of 0.0 and can be adjusted in increments of 0.01. This value is typically used in operations that involve addition or subtraction, providing an offset to the result.

Float Math Output Parameters:

result

The result parameter is the output of the SeargeFloatMath node, representing the final calculated value based on the selected operation and input parameters. This floating-point number is the outcome of applying the specified mathematical formula to the inputs a, b, and c. The result is crucial for further processing or decision-making in your workflow, as it provides the precise numerical value derived from the operation.

Float Math Usage Tips:

• To achieve specific scaling effects, use the a * b operation and adjust the b parameter to control the scaling factor.
• For simple offset adjustments, the a + c or a - c operations can be very effective, allowing you to add or subtract a constant value from a.

Float Math Common Errors and Solutions:

Division by zero error

• Explanation: This error occurs when the a / b operation is selected and the b parameter is set to 0, leading to an undefined result.
• Solution: Ensure that the b parameter is never set to 0 when using the division operation. Adjust b to a non-zero value to avoid this error.

Invalid operation selection

• Explanation: This error occurs if an invalid operation string is somehow passed to the op parameter.
• Solution: Verify that the op parameter is set to one of the predefined operations: a * b + c, a + c, a - c, a * b, or a / b. Ensure that the operation string is correctly specified.
