  6. Vector2i
  7. ========
  8. Vector used for 2D math using integer coordinates.
  9. Description
  10. -----------
  11. 2-element structure that can be used to represent positions in 2D space or any other pair of numeric values.
  12. It uses integer coordinates and is therefore preferable to :ref:`Vector2<class_Vector2>` when exact precision is required.
  13. **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``.
