+### clampNumber
+
+Clamps `num` within the inclusive `lower` and `upper` bounds.
+
+If `lower` is greater than `upper`, swap them. If `num` falls within the range, return `num`. Otherwise return the nearest number in the range.
+
+```js
+const clampNumber = (num, lower, upper) => {
+	if(lower > upper) upper = [lower, lower = upper][0];
+	return (num>=lower && num<=upper) ? num : ((num < lower) ? lower : upper) 
+}
+
+// clampNumber(2, 3, 5) -> 3
+// clampNumber(1, -1, -5) -> -1
+// clampNumber(3, 2, 4) -> 3
+```
