Log (NUMBER)

ComfyUI likes to split numbers into INT and FLOAT, but a lot of workflows hand you a plain NUMBER - the union type that accepts either - and you just want to see what it is. Log (NUMBER) (LogNumber) prints it to the console and passes it through. If the RF Nodes Log family has a "don't make me think about types" member, this is it: one node that logs whatever number arrives, integer or not.

How it works

Identical to the pack's other Log nodes: LogToConsole(prefix, value) writes a cyan line to the terminal running ComfyUI, and the node returns the value unchanged. The passthrough means you can drop it inline on a wire without changing the graph's behavior.

The only real difference from LogFloat and LogInt is the input type. This node accepts NUMBER - the broader, accepts-either type - so it's the one to grab when the source node doesn't commit to INT or FLOAT, or when you're logging a value whose type you're not sure about.

The inputs that matter

• value - a NUMBER (int or float), forceInput, so it must be wired.
• prefix - the label before the value (default Value:). Name it after what you're measuring.

Output: NUMBER - the same value, unchanged.

When you'd use it

Anywhere a number is computed by a node that returns the generic NUMBER type. And there's a practical bonus to the union type: if you're not sure whether some upstream output is an INT or a FLOAT, this node accepts either, so you can log it without the "wrong socket" connection error. That alone has saved me a few frustrating minutes.

Installing RF Nodes

No dependencies, no models. Via ComfyUI Manager search "RF Nodes", or:

cd ComfyUI/custom_nodes
git clone https://github.com/foxtrot-roger/comfyui-rf-nodes

Restart ComfyUI; it's under RF in the menu.

Common issues

• "It's basically LogFloat/LogInt." - Close. Those are typed to a specific input; this one accepts both. For observing a generic NUMBER output, it's the right tool.
• "Logs are invisible." - Console, not browser. Run ComfyUI from a terminal if you want to see the output.
