ComfyUI Node: 多参数学表达式

多参数学表达式:

The MultiIntFormula node is designed to perform mathematical operations on multiple input parameters, allowing you to create complex expressions using basic arithmetic operators such as addition, subtraction, multiplication, division, and modulus. This node is particularly useful for AI artists who need to manipulate numerical data within their workflows, providing a flexible and powerful tool to compute results based on user-defined expressions. By supporting both integer and float types, the node ensures versatility in handling different numerical inputs, and it outputs results in both integer and float formats, catering to various needs in your creative processes.

多参数学表达式 Input Parameters:

expression

The expression parameter is a string input where you define the mathematical formula to be evaluated. This parameter supports a wide range of arithmetic operations, including addition (+), subtraction (-), multiplication (*), division (/), modulus (%), and the use of parentheses for grouping. The expression should be written using English characters and can include multiple variables such as n0, n1, etc., which are defined as optional inputs. This flexibility allows you to craft complex calculations tailored to your specific requirements.

n0

The n0 parameter is an optional input that can be either an integer or a float. It serves as one of the variables in your expression, allowing you to dynamically adjust the calculation based on the value provided. This parameter does not have a predefined default value, so it should be specified if used in the expression.

n1

Similar to n0, the n1 parameter is another optional input that accepts both integer and float values. It acts as an additional variable in your expression, providing further customization and control over the mathematical operations you wish to perform. Like n0, it does not have a default value and should be defined if included in the expression.

多参数学表达式 Output Parameters:

INT

The INT output parameter provides the result of the evaluated expression as an integer. This output is particularly useful when you need a whole number result for further processing or integration into other parts of your workflow. The integer output ensures compatibility with systems or nodes that require integer inputs.

FLOAT

The FLOAT output parameter delivers the result of the evaluated expression as a floating-point number. This output is essential when precision is required, or when the result needs to be used in calculations that involve decimal values. The float output offers greater flexibility and accuracy for complex mathematical operations.

多参数学表达式 Usage Tips:

• Ensure that your expression is correctly formatted using English characters and valid arithmetic operators to avoid syntax errors.
• Utilize the optional n0 and n1 parameters to dynamically adjust your calculations, providing greater flexibility and control over the results.

多参数学表达式 Common Errors and Solutions:

表达式错误

• Explanation: This error occurs when there is a syntax issue or invalid operation in the expression provided.
• Solution: Double-check the expression for any typos, ensure all operators and variables are correctly used, and verify that the expression is syntactically correct.
