Int Operation

Where Float Operation handles the fractional stuff, Int Operation is its integer sibling - and INT is ComfyUI's language for things you count. Batch sizes, step counts, seeds, tile numbers. When a workflow needs "twice the batch" or "half the steps," that's integer math, and that's this node's whole job.

It works exactly like Float Operation: a Python match statement over a +, -, *, / dropdown, two numbers in, one number out. The interesting part is how division behaves. The code computes int(operand_a / operand_b) - it divides as floats, then truncates toward zero. So 7 / 2 gives 3, not 3.5. And -7 / 2 gives -3 - which is not floor division (that would give -4). Truncation, not flooring. If you're comparing step math across nodes or scripts, that distinction occasionally bites.

The inputs that matter:

• operand_a, operand_b - the two INT values. Type them or wire them from an INT output (seed, batch size, step count).
• operator - the dropdown: +, -, *, /.

Output is a single result (INT). Wire it into any INT input - KSampler steps, batch_size, seed arithmetic, tile counts for an upscaling pass. Division is the one you'll actually reach for: "run at half the steps" is just steps / 2. Just remember you lose the remainder, so for finer control you want the pack's float node (or its Int-to-Float converter) and rounding later.

Installing it

Same as the rest of the pack - ComfyUI Manager, search "Mewins Node Pack", install, restart. Or manually:

cd ComfyUI/custom_nodes
git clone https://github.com/efuentesamin/mewins_node_pack

No dependencies to pip and no model files to download - pyproject.toml lists zero runtime deps. The one requirement that can trip you: the pack declares Python >= 3.12, so a ComfyUI running on 3.10/3.11 may fail the version check at install.

Gotchas

• Division by zero is unguarded. Set operand_b to 0 with / selected and the node raises ZeroDivisionError, killing the run. It's the classic "why did my graph die" culprit in this pack.
• Truncation silently drops the remainder. 7 / 2 = 3. If you actually wanted 3.5, you're in the wrong node.
• One operator at a time. Chained math means stacking nodes or using core MathExpression.

Context worth having: this is a small, single-commit pack whose README is still boilerplate ("A list of features"). Don't expect an ecosystem staple - but for one visible integer operation, it does exactly what it says, with zero dependencies to fight and no model downloads lurking.
