Takes absolute value of data stream (i.e. strips sign).  Only supports float, int, and short (not complex).
The abs block converts the input data stream into its absolute value i.e. the negative input values become positive output values and the positive values remain the same at both the input and the output.

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI
This flowgraph shows a sinusoid being passed through the Abs block, producing full-wave rectification.
