 	<description>
-		[Rect2] consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.
+		The [Rect2] built-in [Variant] type represents an axis-aligned rectangle in a 2D space. It is defined by its [member position] and [member size], which are [Vector2]. It is frequently used for fast overlap tests (see [method intersects]). Although [Rect2] itself is axis-aligned, it can be combined with [Transform2D] to represent a rotated or skewed rectangle.
-		It uses floating-point coordinates. If you need integer coordinates, use [Rect2i] instead.
+		For integer coordinates, use [Rect2i]. The 3D equivalent to [Rect2] is [AABB].
-		The 3D counterpart to [Rect2] is [AABB].
+		[b]Note:[/b] Negative values for [member size] are not supported. With negative size, most [Rect2] methods do not work correctly. Use [method abs] to get an equivalent [Rect2] with a non-negative size.
-		Negative values for [member size] are not supported and will not work for most methods. Use [method abs] to get a Rect2 with a positive size.
+		[b]Note:[/b] In a boolean context, a [Rect2] evaluates to [code]false[/code] if both [member position] and [member size] are zero (equal to [constant Vector2.ZERO]). Otherwise, it always evaluates to [code]true[/code].
