aevawhat would you call the inverse of lerp i.e. alpha = (n - low) / (high - low) ?
Karsten Schmidt@aeva I call it `norm()`, because it essentially computes the normalized version of the value in the [lo,hi] interval. Like GLSL, I'm using `mix()` for the actual `lerp` op, and like Houdini VEX, I'm using `fit()` to map a value from [a,b] to [c,d] intervals:
