The Math AB Filter Node enables you to add your own mathematical formula with two input values A and B. It is useful for reducing the amount of nodes and thus saves performance for larger node systems calculating mathematical operations.

The node can be found under Nodes > Filter Nodes > Math > Math AB

## Node properties

### A:

Choose an input node from the drop-down or enter a numeric value.

### B:

Choose an input node from the drop-down or enter a numeric value.

### Math:

Enter here the mathematical formula with the variables A and B you want to calculate.

Usable expressions are "+", "-", "*" and "/", as well as "( )".

## Node control

With Widget Designer version 6, all nodes support so called node commands. Node commands access functions (i.e methods) from a node and / or set a parameter (i.e. property).

Enter "node", followed by the according ID and a dot and a list will pop up showing all available commands for the node. For instance, Node1.TintColor.SetRGB(125,0,255), colors the node in purple.

In addition, the node properties with a parameter ID (the small superscript number) can be edited via the command Node1.SetParam(ID,new Value) or WDNodeSetParam(NodeID,ParamID,Value).

## Node output values

The Node generates the following output:
