Maps a number from one range to another range.

Returns `num` mapped between `outMin`-`outMax` from `inMin`-`inMax`.
|
|
|
|
```js
|
|
const mapNumRange = (num, inMin, inMax, outMin, outMax) =>
|
|
((num - inMin) * (outMax - outMin)) / (inMax - inMin) + outMin;
|
|
```
|
|
|
|
```js
|
|
mapNumRange(5, 0, 10, 0, 100); // 50
|
