I often need to calculate the position of a number $n$ on a scale from $a$ to $b$, represented as a value between $0$ and $1$ (inclusive), as shown below: $ p=\frac{n - a}{b - a} $ Where $a \leq n \leq b \therefore 0 \leq p \leq 1$
Is there a general mathematical term for the percentage value $p$?
Edit: Alternatively, is there a name for the function I used? $F(x)=\frac{x-a}{b-a}$
