-	<brief_description>
-		Outputs a 3D vector based on the result of a floating-point comparison within the visual shader graph.
-	</brief_description>
-	<description>
-		This visual shader node has six input ports:
-		- Port [b]1[/b] and [b]2[/b] provide the two floating-point numbers [code]a[/code] and [code]b[/code] that will be compared.
-		- Port [b]3[/b] is the tolerance, which allows similar floating-point numbers to be considered equal.
-		- Ports [b]4[/b], [b]5[/b], and [b]6[/b] are the possible outputs, returned if [code]a == b[/code], [code]a &gt; b[/code], or [code]a &lt; b[/code] respectively.
