Float to Integer

Float to Integer converts a FLOAT to an INT. Simple conversion node, one input, one output. But here's the wrinkle that makes this worth a warning: the node's own description says "Rounds," and the README says it truncates. The code - which is ground truth - truncates toward zero. 3.7 becomes 3, and -3.7 becomes -3, not -4 as rounding would give you.

When you'd use it

ComfyUI is full of places where one side of the graph wants an integer and the other side hands you a float - dimensions, step counts, batch sizes, seeds, counters. A conversion node is the adapter. If you're computing a value (via a math node, a comparison, a percentage of something) and the thing you're feeding insists on INT, this is the bridge.

How it works

The actual implementation is one line:

result = int(Float)

That's Python's int() on a float, which truncates toward zero. If you genuinely need rounding - 3.7 → 4 - this is not your node, and the mismatch between the description and the behavior is a classic "trust the code, not the label" moment. The Math Operation node in this same pack has a "Round" mode if that's what you actually want.

Inputs:

• Float - a FLOAT input socket (forceInput, so wire it, don't type).

Output:

• Integer - the truncated INT.

Where people get burned

Beyond the rounding surprise, the subtle one is precision loss in the other direction of the pipeline: if you convert early, you lose the fractional part before later math ever sees it. Convert at the last moment - right before the node that needs the integer - and let upstream stay in float land as long as possible.

Also worth knowing: the conversion node family in this pack (Float to Integer, Integer to Float, Integer to String, and the string-conversion siblings) all share the forceInput pattern, so none of them accept typed values. Everything comes from wires.
