String to Int

Seeds are integers. Steps are integers. Resolutions are integers. And half the time the value you actually want to feed in arrives as a string - from a wildcard, a text node, or a file. String to Int parses text into a proper INT, and it's thoughtful about it: it handles "42", and it also handles "3.14" by converting through float first, so decimal-looking text doesn't just explode.

It's part of DebugPadawan's ComfyUI Essentials, a pure-Python utility pack. No models, no GPU - this is int(float(value)) in a box.

How it works

One required input:

• value - the STRING to parse (default "0", single-line)

One output: int_value - the parsed number as an INT.

The implementation runs int(float(value)). The float() step is the clever part: it means "3.14" parses fine and becomes 3 (truncated, not rounded), and "42" becomes 42. It also means scientific notation like "1e3" gives 1000. If the string can't be turned into a number at all, the node raises a ValueError - Cannot convert 'abc' to int - so bad input stops loudly instead of corrupting your graph silently.

Where you'll use it

• Seeds and steps from text. A prompt-builder or wildcard hands you a seed as text; convert before feeding the KSampler.
• Config values. Files and switch nodes that output strings containing integers.
• After math that returns floats. It's the natural companion to Number Round - round to a clean value, then convert to INT for nodes that demand integers.

Installing it

Whole pack, one install. ComfyUI Manager, searching for "DebugPadawans-ComfyUI-Essentials," or:

cd ComfyUI/custom_nodes
git clone https://github.com/DebugPadawan/DebugPadawans-ComfyUI-Essentials

Then restart ComfyUI. Requirements (numpy, torch, opencv-python) are already in stock ComfyUI; no downloads. One naming trap in Manager: this is DebugPadawan's ComfyUI Essentials, not cubiq's "ComfyUI Essentials" - a different, larger pack that's in maintenance mode.

Gotchas

• Truncation, not rounding. "3.9" becomes 3, because int(float("3.9")) chops the fraction. If you want 4, round first (the pack's Number Round does that cleanly).
• It raises on garbage. Unlike String to Boolean, which defaults to True on unknown input, this node will throw on "abc" or "". Fail-fast is good, but validate upstream.
• Negative and exponent forms work ("-7" → -7, "1e3" → 1000) but comma decimals ("3,5") do not.
• Small pack, quiet community; the behavior is simple enough that the source is the doc.
