== Abs Node ==
The Abs Node provides the absolute value of a scalar or of the individual components of vectors. In practice it means removing any negative sign of a value, leaving only the ''absolute'' value.


== ATan2 Node ==

The ATan2 node outputs the arctangent of the division [[#paramA|A]]'''/'''[[#paramB|B]]. If (B,A) defines a (x,y) vector then using this operator returns the angle in radians it does with the x-axis <br/>

'''NOTE:''' ATan2 between multi-channel data types are done per-channel. If ''A'' and ''B'' have different channel amounts a cast is done to match the one with the most amount of channels.

Abs Node

The Abs Node provides the absolute value of a scalar or of the individual components of vectors. In practice it means removing any negative sign of a value, leaving only the absolute value.

Node Parameter Description Default Value
Input Value to be used in the Abs calculation. Only visible if the respective input port is not connected. 0
Input Port Description Type
Input Value to be used in the Abs calculation. Float [1]


  1. ^ Port automatically adapts to all connection types except Sampler types.
