Simple Float Slider - Hundredths Step [LP]

The most boring node in this whole pack, and that's the point. A slider from 0.0 to 1.0 that moves in steps of 0.01, so you get clean, precise values instead of ComfyUI's default float widget rounding weirdness or accidentally typing 0.734829 when you meant 0.73.

What it's for

Anywhere you'd otherwise type a float by hand into a widget - a LoRA weight, an opacity, a blend factor, a denoise strength - this gives you a slider that only ever produces values you can predict, in hundredths increments. It's part of a small family in this pack: the base Simple Float Slider (0.0–1.0, fixed), a "Tenths Step" version for coarser 0.1 increments, and this one for finer 0.01 increments. Which one you want depends purely on how much precision the value you're feeding actually needs - tenths for something like a rough blend, hundredths for something you're tuning finely, like matching a specific opacity value from a reference.

The original functionality here is credited in the README to comfyui-mixlab-nodes by shadowcz007 - worth knowing if you've used mixlab's sliders elsewhere and this one feels familiar.

Inputs and outputs

• number (FLOAT, default 0, min 0, max 1, step 0.01) - the slider itself. Min and max aren't adjustable from the interface; per the README, if you genuinely need a different range you'd have to edit the Python source directly, which most people won't need to do.

Output: FLOAT - the current slider value, ready to wire into whatever expects a float.

Installing it

Through ComfyUI Manager: search "ComfyUI-LevelPixel" (listed as "Level Pixel"), install, restart. Manual: cd ComfyUI/custom_nodes && git clone https://github.com/LevelPixel/ComfyUI-LevelPixel.git, restart ComfyUI. Nothing to download - it's a UI widget node, no dependencies beyond ComfyUI itself.

Common issues

The one real caveat here comes straight from the README, and it's worth reading twice because it's easy to miss: this slider (and its Tenths Step sibling) "work correctly only if you have not changed the value of 'Float widget rounding decimal places' in the ComfyUI settings. If you have changed it, then return the value to 0." That's a global ComfyUI setting, not something in this node - if you've ever tweaked it for another workflow and forgotten about it, you'll see this slider producing values that don't line up with the clean 0.01 increments you expect, and it'll look like the node is broken when it's actually a setting fighting it from outside.

Beyond that, there's nothing exotic here - it's a slider. If you need a range outside 0.0–1.0 (say, a rescale factor that goes up to 16, like Image Overlay's in this same pack), this specific node isn't built for that; look for a general-purpose FLOAT widget or a different node with the range you actually need instead of trying to force this one past its fixed bounds.
