Vector2i
========

Vector used for 2D math using integer coordinates.

Description
-----------

2-element structure that can be used to represent positions in 2D space or any other pair of numeric values.

It uses integer coordinates and is therefore preferable to :ref:`Vector2<class_Vector2>` when exact precision is required.

\ **Note:** In a boolean context, a Vector2i will evaluate to ``false`` if it's equal to ``Vector2i(0, 0)``. Otherwise, a Vector2i will always evaluate to ``true``.
