[Ruckus]

English question: Is there a word for interpolate, but the opposite direction?
For example, say I have min and max, I can get value = interpolate(from = min, to = max, ratio = 50%). But say I have another function anti-interpolate that, given a min, max, and value, it tells me what the ratio is that value is between min and max.

ratio?

[Ruckus]

Are you asking what ratio is or suggesting it as a name?

[Dominaezzz]

Suggesting as a name.

[Ruckus]

It's not a particularly descriptive name. If you see a function called interpolate, you have a reasonable idea of what it is doing. If you see a function called ratio, not so much.

I don't think there is a equivalent English word, however the nearest match would be deconstruct/decompose.

[Ruckus]

I was afraid of that. Thanks for all the suggestions everyone.

I used “deinteroplate” in my lib

[hudsonb]

The “de” prefix sometimes means opposite, for example deconstructing is the opposite of constructing, forestation vs deforestation, etc

[Ruckus]

That does sound better than uninterpolate.
