Why Use double?

Precision: The double method offers a higher precision compared to other data types, making it ideal for decimal calculations, particularly in financial applications.

Compatibility: It is compatible with various database systems, ensuring that your application behaves consistently across different environments.

Conclusion

Defining a column for floating-point numbers in Laravel 8 is straightforward when you use the double method. Whether you are building e-commerce applications, finance tracking systems, or any other apps that require numerical data to include decimal points, this solution will serve you well.

Now that you know how to handle floating numbers effectively, you can confidently set up your data structure in Laravel and avoid issues related to data overflow or inaccuracies. Happy coding!
