🔢 Float Input

ComfyUI already has a float input widget on a hundred nodes, so why does a pack ship its own? The answer is in one input: name. This is a bare input node - value, min, max, step, and out comes a FLOAT - but the name field exists for ComfyUI web interfaces that generate dynamic HTML forms from workflow inputs. Name it denoise_strength and a web UI can render a proper labeled slider for it, driven by the min/max/step you set. In the desktop app it's a regular widget; the node becomes genuinely useful when your workflow is being served through a web frontend where users should only touch certain values.

Inputs

• name - the identifier the web interface uses for the field. Make it human-readable; it becomes the label.
• value - the float that comes out. Range is enormous (±1e10) so this works as a raw constant too.
• min / max - validation bounds for the web form (and the widget's slider range).
• step - the slider increment, default 0.01.

Output is a FLOAT. Wire it into any node that takes a float - denoise, cfg, upscale_by, strength, whatever.

The honest take

For the desktop ComfyUI user, this is a slightly redundant convenience node: you can get a float constant from half a dozen packs, and even the base UI handles sliders fine. Where it pulls weight is (a) template workflows that are meant to be filled in by non-technical users through a web UI, and (b) keeping a workflow self-documenting - a named input node reads better than an anonymous constant when you're sharing a graph. The pack ships a whole family of these (Int, Float, Boolean, String), so if you're building templates on this pack you get a consistent input style across all of them.

If you just want a number in a graph and you're not sharing via a web form, skip it and use a stock constant. If you're building a template workflow someone else will run, this is the tidy choice.
