How to store float values efficiently in Laravel Eloquent ?

If you want to store price in dollars such as 4.99, just store it as integer not float in database (499). And in your model add this function.

public function getPriceAttribute(){
    return floatval(number_format($this->attributes["price"] / 100, 2));
}

When you get the price, it is 4.99 , but it is stored as 499. This saves a huge space when you have more than 10k records in database.

The optimization aspect is to store double float values as integers in database.
