How would I do this?

Say I have two values assigned to two respective keys, one “high” and one “low”. Now, I have a new key somewhere in between those two extremes. How would I retrieve a value based on how close/far the new key is to either of the extremes? For example, let’s say I have 1 assigned to 10 and 2 assigned to 20. How could I make 1.5 return 15?

function assignNumber(n)
	return n * 10
end

print(assignNumber(1)) -- -> 10
print(assignNumber(1.5)) -- -> 15
print(assignNumber(1.8)) -- -> 18
print(assignNumber(2)) -- -> 20

Is this what you meant?

What you’re describing is linear interpolation.

local function Lerp(Start, End, Alpha)
	return Start + ((End - Start) * Alpha)
end

print(Lerp(10, 20, 0.5)) --15

Unlike the previous solution this is compatible with any set of values.

No, that was just an example. Like Forummer said, I want something compatible with any number. Thank you, though!
