FloatSlider-NYJY

Most float inputs in ComfyUI are number boxes - you type 0.45 and squint. FloatSlider-NYJY gives you an actual slider widget: a number value you drag between min_value and max_value, with a precision dropdown that controls the step size. Set a cfg range of 0 to 20 and slide it; set a denoise range of 0 to 1 and slide it. It's a tiny ergonomics node - the whole point is that dragging beats typing - and it pairs naturally with any parameter input in your workflow.

How it works

The slider widget carries a default of 1.0 and a step defined by the precision you pick. On run, the node rounds the dragged value to that precision and hands it out: with precision 0.1 you get round(number, 1), with 0.01 two decimal places, 0.001 three, and 1 snaps to a whole number. It also emits an INT output alongside the FLOAT, computed by ceiling the value - so a dragged 0.7 gives FLOAT 0.7 and INT 1. If you only care about the float, ignore the int output; if you're feeding a steps-style integer input, it's a convenience you'll appreciate.

Inputs and outputs

• number - the slider itself, FLOAT, default 1, step 0.1. The value you drag.
• min_value - the slider's lower bound (FLOAT, default 0).
• max_value - the upper bound (FLOAT, default 1).
• precision - dropdown: 1, 0.1, 0.01, or 0.001. Controls rounding of the FLOAT output.

Outputs: FLOAT (the rounded value) and INT (the value ceilinged to an integer).

Installing

Standard pack install: ComfyUI Manager → Install via Git URL → https://github.com/aidenli/ComfyUI_NYJY, restart. Nothing else to it.

Notes from real use

Set min_value/max_value to a sensible range for the parameter you're driving - a slider labeled denoise that runs 0–1 is useful; the same slider running 0–100000 is a trap. The precision dropdown is the "how fiddly do I want this" control; 0.01 is the sweet spot for most sampling parameters. One quirk worth knowing: because the slider itself is a number input rendered as a widget, it's a node that's at its best in the interactive phase of a workflow - tune with the slider, then lock the value in. It's not a scheduler and not a converter; it's just a nicer way to hold a number. For that, it does the job with zero fuss.
