create INT

ComfyUI will hand you numbers as text all the time - a filename with a frame number in it, a wildcard, a JSON value - and most math nodes will look at the string "42" and shrug. create INT is the pack's answer: a box where you type a number and get a real integer out, with a genuinely clever bonus nobody expects.

What it does

You type a string into the value field, and the node runs Python's int(value, 0) on it. The 0 there is the interesting part - it tells Python to auto-detect the base from the prefix. So:

• "42" → 42
• "0b1010" → 10 (binary)
• "0o17" → 15 (octal)
• "0x1F" → 31 (hex)

Type 0x1F into a box, get 31 out the other side. That's the whole reason this node exists separately from a plain cast: it's the only INT node in the pack that parses prefixed number strings for you, which is invaluable if you're dealing with hex-encoded values from files, configs, or APIs.

The one thing it won't do is decode ones' complement notation - the README and the source are explicit that it doesn't handle it, because the data size is unknown. Don't expect ~5 style input to work.

Inputs and outputs

• value - a string widget (technically the wildcard * type, default "0"). Type your number, prefix and all.
• Output INT - the parsed integer.

If the string isn't a valid integer in the detected base, the node raises an error. "hello" or "12.5" will fail loudly rather than guess.

Install

From the Basic data handling pack. ComfyUI Manager → search "Basic data handling" → install → restart. Or:

cd ComfyUI/custom_nodes
git clone https://github.com/StableLlama/ComfyUI-basic_data_handling

then restart ComfyUI. No dependencies, no models.

Where you'll actually use it

Two spots. First, converting text fields to math-able integers - create INT feeding an IntAdd or a comparison node. Second, the hex path: parse 0x-prefixed values from a config or a file, and pair it with to bytes / from bytes when you're shuffling binary data around. If you only ever need base-10 parsing, the plain cast to INT is enough; reach for this one the moment prefixes enter the picture.
