  8. =====
  9. A built-in type for floating-point numbers.
  10. .. rst-class:: classref-introduction-group
  11. Description
  12. -----------
  13. The **float** built-in type is a 64-bit double-precision floating-point number, equivalent to ``double`` in C++. This type has 14 reliable decimal digits of precision. The maximum value of **float** is approximately ``1.79769e308``, and the minimum is approximately ``-1.79769e308``.
  14. Many methods and properties in the engine use 32-bit single-precision floating-point numbers instead, equivalent to ``float`` in C++, which have 6 reliable decimal digits of precision. For data structures such as :ref:`Vector2<class_Vector2>` and :ref:`Vector3<class_Vector3>`, Godot uses 32-bit floating-point numbers by default, but it can be changed to use 64-bit doubles if Godot is compiled with the ``precision=double`` option.
  15. Math done using the **float** type is not guaranteed to be exact and will often result in small errors. You should usually use the :ref:`@GlobalScope.is_equal_approx<class_@GlobalScope_method_is_equal_approx>` and :ref:`@GlobalScope.is_zero_approx<class_@GlobalScope_method_is_zero_approx>` methods instead of ``==`` to compare **float** values for equality.
