Documentation for SimpleMathCondition+ Node

Overview

The SimpleMathCondition+ node is a utility node in the ComfyUI_essentials repository that allows users to conditionally execute mathematical expressions based on the evaluation of a given condition. It is designed to perform operations similar to a ternary operator, where a condition is evaluated first, and then either one of two provided math expressions is executed based on the result of the evaluation.

Functionality

What This Node Does

• The SimpleMathCondition+ node evaluates a given condition and selects between two mathematical expressions to execute.
• The node returns the results of the selected expression as both an integer and a floating-point number.
• This is useful for scenarios where a decision needs to be made between two values or operations based on some condition, making it flexible for dynamic workflows.

Inputs

Required Inputs

1. Evaluate: A condition that determines which mathematical expression will be executed. This input can be of any type that evaluates to a boolean (e.g., integer, float, boolean).

2. On True: The mathematical expression to be evaluated if the condition in "Evaluate" is true. The expression should be provided as a string.

3. On False: The mathematical expression to be evaluated if the condition in "Evaluate" is false. This should also be provided as a string.

Optional Inputs

• A, B, C: Additional optional variables that can be used within the mathematical expressions. These can be set to any type and default to 0.0. They allow for more complex expressions by providing additional input values.

Outputs

• The node produces two outputs based on the evaluation of the selected mathematical expression:
  1. Integer: The result of the evaluation converted to an integer.
  2. Float: The result of the evaluation as a floating-point number.

Usage in ComfyUI Workflows

The SimpleMathCondition+ node is useful in ComfyUI workflows for regulating operations that depend on dynamic conditions or user input. For example, it can be applied in scenarios where:

• An operation route needs selection based on user preferences or predefined criteria.
• Mathematical evaluation depends on system states or real-time parameters.

By integrating this node, users can introduce conditional logic to their UI interactions, allowing for more responsive and personalized user experiences.

Special Features or Considerations

• Flexible Conditions: It supports a wide range of evaluation conditions and can interpret both numerical and boolean inputs.
• Expression Parsing: The node is built to parse and then execute mathematical expressions provided as strings, allowing seamless integration of math logic without coding.
• Extended Inputs: With additional variables like A, B, and C, users can design intricate mathematical formulas tailored to specific conditions.

This makes the SimpleMathCondition+ node a powerful addition to ComfyUI workflows for any situation requiring conditional logic or decision-making processes.
