See ...

@MxHeppa My apologies for the delayed response here!

The below is from our resident Photo Expert:

"Procedural Texture just uses the 0-1 range (0 being black, 1 being SDR white). Using values greater than 1 has relevance for 32-bit unbounded HDR documents, and I think functions like max() might return unbounded values >1 within that context.
Generally speaking though, it’s just floats within 0-1. This applies to other values for functions, like if you’re using lerp(), the third parameter is the balance between the two given values, and setting this to 0.5 will be an even split.
You can of course use greater values for function parameters, things like noise functions (perlin etc)."

Does this help, or are you referring to pixel values?
