4 Floats

4 Floats lets you set four float values on one node and send them out together as a single float list. It's the "pack" half of a pack/unpack pair - you bundle four numbers into one wire here, then pull them back apart downstream with 4 Floats from List (FloatListInterpreter4). The point is tidiness: instead of four separate wires snaking across your graph, one list wire carries the whole set.

Where this actually earns its place is any workflow that juggles a handful of related weights or parameters - think a set of block or region strengths, a few multipliers, or values you want to keep grouped and route as a unit. It's part of ComfyUI_Mira, mirabarukaso's collection of small workflow-glue nodes, in the Numeral family. Like a lot of Mira, it's built around the author's own regional-conditioning and character-select workflows, where passing tidy little bundles of numbers around beats a spaghetti of single floats.

How it works

You get four float widgets on the node. It collects those four values into a single ordered FLOAT_LIST and outputs that. No math, no transformation - it's a grouping node. The order you enter them is the order they come out, which matters when you unpack them.

The inputs and outputs that matter

• float_1, float_2, float_3, float_4 - the four values, each ranging -10 to 10 (default 1, step 0.01).
• float_list (output) - a single FLOAT_LIST carrying all four, wired into 4 Floats from List or any node that accepts a float list.

The natural partner is FloatListInterpreter4, which takes this list back apart into four individual FLOATs at the other end of your graph.

Installing it

ComfyUI Manager: search ComfyUI_Mira, install, restart. Or clone:

cd ComfyUI/custom_nodes && git clone https://github.com/mirabarukaso/ComfyUI_Mira.git

then restart. If loading errors, run pip install -r requirements.txt in the ComfyUI_Mira folder. Node appears under Mira/Numeral.

Common issues

• A list is not four separate floats. You can't wire this straight into a node expecting a single FLOAT - it carries all four. Unpack it first with 4 Floats from List (or feed it to something that genuinely takes a list).
• Order is meaningful. Whatever order you set here is the order the unpacker reads. Keep the two ends consistent or your values land in the wrong slots.
• It's organizational, not functional. This node doesn't do anything to the numbers. If your graph only has one or two floats, you don't need to bundle them - reach for 1 Float instead. Bundling pays off when you're routing a group of related values together.
