ComfyUI Node: ⚙️ CR Math Operation

⚙️ CR Math Operation:

The CR Math Operation node is designed to perform a variety of mathematical operations on a given input value. This node is particularly useful for AI artists who need to apply mathematical transformations to their data within the ComfyUI framework. By leveraging this node, you can easily compute trigonometric functions like sine, cosine, and tangent, as well as other mathematical operations such as square root, exponential, logarithm, negation, and absolute value. The node simplifies complex mathematical computations, making it easier to integrate these operations into your creative workflows without requiring deep technical knowledge.

⚙️ CR Math Operation Input Parameters:

a

This parameter represents the input value on which the mathematical operation will be performed. It is a numerical value that can be either an integer or a floating-point number. The value of a directly impacts the result of the operation, as it serves as the operand for the selected mathematical function. There are no specific minimum or maximum values for this parameter, but it should be within a reasonable range for the chosen operation to avoid computational errors.

operation

This parameter specifies the type of mathematical operation to be applied to the input value a. The available options are sin, cos, tan, sqrt, exp, log, neg, and abs. Each option corresponds to a different mathematical function: sin for sine, cos for cosine, tan for tangent, sqrt for square root, exp for exponential, log for logarithm, neg for negation, and abs for absolute value. The choice of operation determines the nature of the transformation applied to the input value. There are no default values, and you must select one of the specified operations.

decimal_places

This parameter defines the number of decimal places to which the result of the mathematical operation will be rounded. It is an integer value that controls the precision of the output. The minimum value for decimal_places is 0, which means no decimal places, and the maximum value can be set according to your precision requirements. The default value is typically set to a reasonable number of decimal places to balance precision and readability.

⚙️ CR Math Operation Output Parameters:

result

This parameter represents the output value resulting from the specified mathematical operation applied to the input value a. The result is a numerical value rounded to the specified number of decimal places. It is the primary output of the node and reflects the transformation defined by the chosen operation.

show_help

This parameter provides a URL link to the help documentation for the CR Math Operation node. The link directs you to a detailed guide on the node's usage, available at https://github.com/Suzie1/ComfyUI_Comfyroll_CustomNodes/wiki/Other-Nodes#cr-math-operation. This resource is valuable for users seeking additional information or troubleshooting tips.

⚙️ CR Math Operation Usage Tips:

• Ensure that the input value a is within a reasonable range for the selected operation to avoid computational errors, especially for functions like log and sqrt which have domain restrictions.
• Use the decimal_places parameter to control the precision of your results, balancing between accuracy and readability based on your specific needs.
• Refer to the provided help URL for detailed documentation and examples to better understand the node's capabilities and potential applications.

⚙️ CR Math Operation Common Errors and Solutions:

⚙️ CR Math Operation: Unsupported operation.

• Explanation: This error occurs when an invalid or unsupported operation is specified in the operation parameter.
• Solution: Ensure that the operation parameter is set to one of the supported values: sin, cos, tan, sqrt, exp, log, neg, or abs.

ValueError: math domain error

• Explanation: This error typically occurs when the input value a is outside the valid domain for the selected mathematical operation, such as a negative value for sqrt or a non-positive value for log.
• Solution: Verify that the input value a is within the valid range for the chosen operation. For example, ensure a is non-negative for sqrt and positive for log.
