Bool To Int JK🐉

Booleans are great for toggles and switches, useless for arithmetic. CM_BoolToInt is the one-liner bridge: feed it a BOOLEAN, get an INT - True → 1, False → 0. That's the entire node, and the trick is how often you need it.

Why convert a boolean to a number?

Because a 0/1 is a multiplier, a gate, and an index all at once:

• Multiply a strength by on/off. Want a detail pass at strength 0.6 that a toggle can disable? Wire the toggle through this node into a float math node and multiply. Disabled = 0 × anything = nothing runs.
• Index into a list or switch. A two-way switch keyed by an int takes 0 or 1 - a boolean converted cleanly drives it.
• Build counters. Sum a bunch of condition results and you get "how many of these conditions are true," a useful number for branching logic.

Input is a (BOOLEAN), output is INT. The sibling conversion in the other direction - CM_IntToBool, where 0 → False and anything non-zero → True - completes the round trip.

Installing it

It's one node in the ComfyUI-JakeUpgrade pack:

cd ComfyUI/custom_nodes
git clone https://github.com/jakechai/ComfyUI-JakeUpgrade
cd ComfyUI-JakeUpgrade
# Windows standalone: install.bat
# or: python_embeded\python.exe -s -m pip install -r requirements.txt
pip install -r requirements.txt   # non-Windows

Or ComfyUI Manager, search "JakeUpgrade", install, restart. Nothing to download.

Gotchas

• It converts, it doesn't coerce mid-expression. Wire the boolean in before arithmetic; there's no "true counts as 1" magic inside other math nodes in this pack.
• Use it with the pack's condition nodes. An Int or Float condition spits out a boolean; converting that to 0/1 and multiplying is the cleanest way to turn a condition into a continuous influence instead of a hard gate.
• Manager's JakeUpgrade / IPAdapter_plus conflict warning is a false positive from the pack's replacement/ folder.
• ComfyUI-MultiGPU causes CUDA errors with recent ComfyUI - disable it per the README.
