.. _class_Vector4:

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``.
