to number

ComfyUI workflows love to pass numbers around as strings - prompt-extracted values, filenames, config text. Eventually something wants a real NUMBER, FLOAT, or INT socket. To number is the bridge: it takes one STRING and emits it three ways at once - number, float, and roundInt - so you can grab whichever type your downstream node demands without re-casting.

It sounds trivial, and mostly it is. But there's a trap baked into the implementation that you'll hit the first time you feed it a decimal, so read the gotcha before you wire it up.

How it works

The node runs three conversions on your text:

• number - int(text)
• float - float(text)
• roundInt - int(round(float(text)))

The outputs are ordered number, float, roundInt. For an integer string like "42" all three agree (42, 42.0, 42). For a decimal string like "3.7", the story changes: float gives 3.7, roundInt gives 4, but number - int("3.7") - throws a ValueError. Python's int() doesn't accept decimal-point strings. So the number output is only safe for integer-formatted text, and a decimal string will make the whole node error, not just that output.

Inputs and outputs

• text - STRING, the numeric text, default ""
• Outputs: number (NUMBER), float (FLOAT), roundInt (INT)

Installing it

# ComfyUI Manager: search "ymc suite" and install ymc-node-suite-comfyui
# or:
cd ComfyUI/custom_nodes
git clone https://github.com/YMC-GitHub/ymc-node-suite-comfyui

Restart after installing. Dependencies are four small pure-Python PyPI helpers that self-install; no models, no GPU footprint.

Gotchas

• Don't feed decimals if you only need the number output. int("3.7") crashes the node. For decimal text, reach for the float or roundInt outputs, which handle it fine.
• Empty text errors too - int("") is a ValueError. Give it a real default or guard the source.
• The is round to x / switch a and b (isRoundTo) nodes do their rounding internally and take strings directly. If your only goal is a rounding comparison, you can skip this conversion entirely.
• WAS-conflict note as with the rest of the pack: if WAS Node Suite is installed too, Manager may flag shared node names between the packs.
