+### mapNumRange
+
+Maps a number from one range to another range.
+
+Returns `num` mapped between `outMin`-`outMax` from `inMin`-`inMax`.
+
+```js
+const distance = (num, inMin, inMax, outMin, outMax) => (num - inMin) * (outMax - outMin) / (inMax - inMin) + outMin;
+```
+
+```js
+mapNumRange(5,0,10,0,100); // 50
+```
