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? $F(x)=\frac{x-a}{b-a}$

    You can say that $p$ is the result of **scaling** $x$ in the interval $[a,b]$.2012-09-20
