Vector4
=======
A 4D vector using floating point coordinates.
.. rst-class:: classref-introduction-group
Description
-----------
A 4-element structure that can be used to represent 4D coordinates or any other quadruplet of numeric values.
It uses floating-point coordinates. By default, these floating-point values use 32-bit precision, unlike :ref:`float<class_float>` which is always 64-bit. If double precision is needed, compile the engine with the option ``precision=double``.
See :ref:`Vector4i<class_Vector4i>` for its integer counterpart.
\ **Note:** In a boolean context, a Vector4 will evaluate to ``false`` if it's equal to ``Vector4(0, 0, 0, 0)``. Otherwise, a Vector4 will always evaluate to ``true``.

Operator Descriptions
---------------------
.. _class_Vector4_operator_neq_Vector4:
.. rst-class:: classref-operator
:ref:`bool<class_bool>` **operator !=** **(** :ref:`Vector4<class_Vector4>` right **)**
Returns ``true`` if the vectors are not equal.

\ **Note:** Vectors with :ref:`@GDScript.NAN<class_@GDScript_constant_NAN>` elements don't behave the same as other vectors. Therefore, the results from this operator may not be accurate if NaNs are included.

:ref:`bool<class_bool>` **operator <** **(** :ref:`Vector4<class_Vector4>` right **)**
Compares two **Vector4** vectors by first checking if the X value of the left vector is less than the X value of the ``right`` vector.
