# Absolute Value (G Dataflow)

Returns the absolute value of the input.

## x

An input to this operation.

This input supports waveforms and any data type that contains only numbers, such as scalar numbers, arrays or clusters of numbers, arrays of clusters of numbers, and waveforms. x cannot be an unsigned integer because unsigned integers represent only non-negative integers.

Data Type Changes on FPGA

When you add this node to a document targeted to an FPGA, this input has a default data type that uses fewer hardware resources at compile time.

## absolute value

The absolute value of the input.

When x is of the form x = a + b i, that is, when x is complex, the following equation defines abs:
$abs\left(x\right)=\sqrt{{a}^{2}+{b}^{2}}$
