 Reverses a number.
-Use `Object.prototype.toString()` to convert number to a string.
-Use the split function `String.prototype.split()` to convert string to array and `Array.prototype.reverse()` to reverse the order of the characters in the string.
-Combine characters to get a string using `String.prototype.join('')`.
-Use the `parseFloat()` to convert string to a number and use `Math.sign()` to preserve the signum value of the number.
-_Note_: Here `parseFloat()` is used instead of `parseInt()` so floating point numbers are properly handled.
