		<h3>[method:Float smoothstep]( [param:Float x], [param:Float min], [param:Float max] )</h3>
		<p>
		[page:Float x] - The value to evaluate based on its position between min and max. <br />
		[page:Float min] - Any x value below min will be 0.<br />
		[page:Float max] - Any x value above max will be 1.<br /><br />
