Returns the polar components of a complex number.

Given z in rectangular form z = a + b*i*, this node converts the polar components of
$z=r*\mathrm{cos}(theta)+i\text{\hspace{0.17em}}r*\mathrm{sin}(theta)$ according to the following equations:

## z

The complex number.
This input supports complex numbers, clusters of complex numbers, arrays of complex numbers, and arrays of clusters of complex numbers.

Data Type Changes on FPGA

When you use this node on the FPGA or simulated FPGA, the data type for this input changes to a fixed-point number. This change allows LabVIEW to know the size of the input at compile time.

## r

The distance from the origin to the point, *z*.

## theta

The angle for the line, *r*, from the origin to the point, *z*, in radians.
