Hey so i have a simple question

can i get mathf.inverselerp to return a value between -1 and 1 instead of 0 and 1?

Thanks ~Scott

Multiply by 2 and subtract 1. A little less precise, but it will pretty much never matter. Overall this kind of conversion is a common pattern.

```
value = 2 * Mathf.lerp(from, to, t) - 1;
```

Would this work?

```
float originalLerp = Mathf.InverseLerp(a, b, x);
float specialLerp = Mathf.Lerp(-1, 1, originalLerp);
```

I think `specialLerp`

holds what youâ€™re looking for.

Lerp(from, to, x) = from(1-x)+to*x

lerp-from=x(to-from)

(lerp-from)/(to-from)=x

so define your own function as

```
public float InverseLerp(float from, float to, float value){
if(to!=from){
return Mathf.Clamp((value-from)/(to-from), -1f, 1f);
}
return 0;
}
```
