<brief_description>
Vector used for 2D math using integer coordinates.
</brief_description>
<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 [Vector2] when exact precision is required.
[b]Note:[/b] In a boolean context, a Vector2i will evaluate to [code]false[/code] if it's equal to [code]Vector2i(0, 0)[/code]. Otherwise, a Vector2i will always evaluate to [code]true[/code].

<operator name="operator %">
<return type="Vector2i" />
<argument index="0" name="right" type="Vector2i" />
<description>
Gets the remainder of each component of the [Vector2i] with the components of the given [Vector2i]. This operation uses truncated division, which is often not desired as it does not work well with negative numbers. Consider using [method @GlobalScope.posmod] instead if you want to handle negative numbers.
[codeblock]
print(Vector2i(10, -20) % Vector2i(7, 8)) # Prints "(3, -4)"
