Int To Bool JK🐉

The inverse of "True becomes 1": CM_IntToBool takes an INT and returns True when it's non-zero, False when it's exactly zero. One input, one BOOLEAN output, no other options. It's the node that lets a number decide something.

When a number should make a decision

ComfyUI has plenty of places that output numbers but where you really want a yes/no:

• A node reports a count (faces detected, frames, LoRAs in a stack) and you want "did we get any?" - convert and feed a switch.
• An index or ID from a list operation - is it 0, or is it something real? Non-zero → true is the "there's actually an entry here" test.
• You have integer math (say, seed % 2) and want its result as a branch: even/odd from arithmetic feeding a boolean input.

A clean pattern: compute something in CM_IntBinaryOperation or CM_IntUnaryOperation, pipe it through this node, and drive a Bool gate or switch with it. Combined with CM_BoolToInt you can go number → decision → number again, which is how a lot of self-adjusting graphs end up wired.

Installing it

Ships with ComfyUI-JakeUpgrade:

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.

Gotchas

• This is strict a != 0 - and yes, that's Python truthiness. Negative numbers are True. That's usually what you want ("any value"), but if you meant "positive," check CM_IntUnaryCondition's IsPositive instead.
• The exact-zero case is the trap. If your upstream math can produce 0 when you expected "something," this node will quietly say False. Pair it with a condition node when the boundary matters.
• Manager's JakeUpgrade / IPAdapter_plus conflict warning is a false positive from the pack's replacement/ folder.
• ComfyUI-MultiGPU causes CUDA errors on recent ComfyUI; the README says to disable it.
