A comprehensive suite of utility nodes for ComfyUI, designed to perform scientific calculations, data type conversions, and complex unit conversions directly within your workflows.

This project was born from a simple idea: to integrate powerful and flexible calculation tools into the core of image generation, enabling unprecedented control and automation.

✨ Features

This suite includes a diverse range of nodes, all organized under the main CalculatorPro category in ComfyUI.

Sub-category: `Math`

🧮 Scientific Calculator: A powerful three-input (a, b, c) tool capable of performing a wide range of operations:
- Basic arithmetic (+, -, *, /).
- Power (^), modulo (mod).
- Trigonometric functions (sin, cos, tan).
- Square root, logarithm, absolute value, rounding.
- Comparisons (min, max).

Sub-category: `Converters`

🔧 Universal Converter: The Swiss Army knife of data conversion. Provide any input (FLOAT, INT, STRING, or BOOLEAN) and get all four types as output.
💱 Manual Rate Converter: Perfect for currency conversions or any other calculation based on a custom rate. Multiply or divide an amount by an exchange rate.
📏 Length Converter: Convert between dozens of units, from millimeters to parsecs, including feet, inches, and nautical miles.
⚖️ Mass Converter: Easily switch from grams to tons, including pounds, ounces, and even stones.
💧 Volume Converter: Convert liters, cubic meters, gallons, pints, and even kitchen units like tablespoons.
💾 Data Converter: Clearly distinguish between SI units (megabyte, 10⁶) and binary units (mebibyte, 2²⁰), from bit to petabyte.
⏱️ Time Converter: Convert seconds to years, including hours, months, and even Planck time.

🛠️ Installation

Method 1: Git Clone (Recommended)

Open a terminal or command prompt.
Navigate to the custom_nodes folder of your ComfyUI installation.
```
cd /path/to/your/ComfyUI/custom_nodes/
```
Clone this repository:
```
git clone https://github.com/orion4d/Calculator_Pro.git
```
(Don't forget to replace https://YOUR_GITHUB_URL_HERE.git with your repository's actual URL!)
Restart ComfyUI.

Method 2: Manual

Click the green <> Code button at the top of this page, then Download ZIP.
Extract the contents of the ZIP archive.
Place the resulting folder (e.g., scientific_calculator) into the custom_nodes folder of your ComfyUI installation.
Restart ComfyUI.

🚀 Usage Examples

The power of these nodes lies in their ability to dynamically drive other parts of your workflow.

Example 1: Controlling a KSampler Parameter

Use the Scientific Calculator to compute a value (e.g., 1 / 3 to get 0.333...). Connect the result (FLOAT) output to the denoise input of a KSampler for precise control.

Example 2: Calculating Image Dimensions

Use the Calculator to determine a width and height (e.g., width = 1024, height = width * 0.75). Then, use the Universal Converter to convert the FLOAT results to INT and connect them to the width and height inputs of an Empty Latent Image node.

Example 3: Converting for Prompts

Use the Length Converter to convert 1.80 (meters) to Pied (ft). Connect the output_str to a node that assembles prompts to dynamically add "a 5.9-foot tall man" to your text.
