	<brief_description>
		Vector used for 3D math using integer coordinates.
	</brief_description>
	<description>
		3-element structure that can be used to represent positions in 3D space or any other pair of numeric values.
		It uses integer coordinates and is therefore preferable to [Vector3] when exact precision is required.
		[b]Note:[/b] In a boolean context, a Vector3i will evaluate to [code]false[/code] if it's equal to [code]Vector3i(0, 0, 0)[/code]. Otherwise, a Vector3i will always evaluate to [code]true[/code].

				Gets the remainder of each component of the [Vector3i] with the components of the given [Vector3i].

Consider using [method @GlobalScope.posmod] instead if you want to handle negative numbers.
