	<brief_description>
		A 2D vector using integer coordinates.
	</brief_description>
	<description>
		A 2-element structure that can be used to represent 2D grid coordinates or any other pair of integers.
		It uses integer coordinates and is therefore preferable to [Vector2] when exact precision is required. Note that the values are limited to 32 bits, and unlike [Vector2] this cannot be configured with an engine build option. Use [int] or [PackedInt64Array] if 64-bit values are needed.
		[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].
