Welcome to the fascinating world of game development with the Godot 4 engine! Today, we will delve into the integral game development concept of the float class. If you’ve ever wondered how to create realistic physics or detailed movements in your game, the answer lies in understanding and mastering this fundamental class.
Floats are the backbone of many operations in game development, from character movements to complex physics calculations. They’re the secret ingredient that adds depth and realism to your gaming world. So, let’s embark on this exciting journey to decode the mystery of the float class in Godot 4.

What is the float class?
The float class in Godot 4 is a built-in type for floating point numbers. It’s a 64-bit double-precision floating-point number, equivalent to double in C++. This type has 14 reliable decimal digits of precision, allowing for a wide range of values.
Do note that many methods and properties in Godot 4 use 32-bit single-precision floating-point numbers instead, which have 6 reliable decimal digits of precision. This is especially important for data structures such as Vector2 and Vector3.
What is the float class used for?
Floats are used for creating precise calculations in game development. They’re essential for any operation that requires decimal numbers, such as speed, rotation, and scaling.
However, keep in mind that math done using the float type is not guaranteed to be exact and will often result in small errors. Therefore, it’s recommended to use the @GlobalScope.is_equal_approx and @GlobalScope.is_zero_approx methods instead of == to compare float values for equality.
Why should I learn about the float class?
Understanding the float class is crucial for any aspiring game developer. It’s a fundamental building block for creating realistic movements and physics in your games. By mastering the float class, you’ll have a powerful tool in your game development arsenal, allowing you to bring your game ideas to life with precision and depth.
