		+	== Overview ==
		+	The Divide family of nodes allows you to divide the colour/scalar/vector coming into the Main Input by the color/scalar/vector coming into Input 2. The division is component-wise, for example with a colour:
		+	<ul>
		+	Input.red divided by Input 2.red <br /n>
		+	Input.green divided by Input 2.green <br /n>
		+	Input.blue divided by Input 2.blue <br /n>
		+	</ul>
		+
		+
		+	The Divide family of nodes safely handles “division by zero”, which is an invalid operation. In the case of division by zero the node will divide the value by epsilon, which is a very small number greater than zero. This results in a very large valid number output from the node and ensures that your node network will continue to work. If this was not handled by the nodes, the result might be an invalid number, causing problems in the rest of the node network, or the application might even crash.
		+
		+
		+	In the graphs below, you can see the mathematical effect of the Divide family of nodes on a given value from the Main Input. When the value assigned to Input 2 is:
		+	<ul>
		+	-1.0, the value of the node’s output is the inverse, or mirror, of the Main Input values. <br /n>
		+	0.5, the value of the nodes output is twice as great as the Main Input values. <br /n>
		+	1.0, the value of the node’s output is the same as that of the Main Input values. <br /n>
		+	2.0, the value of the node’s output is half that of the Main Input values. <br /n>
		+	</ul>
		+
		+
		+	[[File: DivideFamily_00_Chart.jpg \| none\|800px\|A comparison of the Divide family of node’s output to that of the Main Input, as the value of Input 2 is changed.]]
		+
		+
		+	A natural use of the Divide Vector node would be to provide a way to scale a feature when a scale-type parameter is not available. For example, the Sin Scalar node has only a Main Input. In the example below, by inserting a Divide Vector node between it and the Get Position in Texture node, the scale of the Sin can be adjusted.

		+	\|}
		+	</ul>
		+
		+
		+	All nodes in this family have only one setting, which lets you assign a shader or function nodes for Input 2.
		+
		+	'''Settings:'''
		+
		+	*'''Name:''' This setting allows you to apply a descriptive name to the node, which can be helpful when using multiple Divide Vector nodes in a project.
		+	*'''Enable:''' When checked, the node is active and the division operation will take place. When unchecked the values assigned to its Main Input, if any, are passed through, otherwise a value of 0 is passed through.
		+	*'''Input 2:''' The values from the shader or function nodes assigned to this setting are used as the divisor to the Main Input values. When nothing is assigned, the Main Input values, if any, are passed through. If the Main Input is unassigned, the output from the node is 0.
