Perform various mathematical operations on input values for AI artists in ComfyUI, including trigonometric functions and more.

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.

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.

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.

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.

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.

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.

- 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.

**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`

.

**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`

.
