+Reverses a number.
+
+- Use `Object.prototype.toString()` to convert `n` to a string.
+- Use `String.prototype.split('')`, `Array.prototype.reverse()` and `String.prototype.join('')` to get the reversed value of `n` as a string.
+- Use `parseFloat()` to convert the string to a number and `Math.sign()` to preserve its sign.
+
+```js
+const reverseNumber = n => 
+  parseFloat(`${n}`.split('').reverse().join('')) * Math.sign(n);
+```
+
+```js
+reverseNumber(981); // 189
+reverseNumber(-500); // -5
+reverseNumber(73.6); // 6.37
+reverseNumber(-5.23); // -32.5
+```
