Converts the rectangular components of a complex number into its polar components.

This node converts the rectangular components to polar components using the following equations:

$r=\sqrt{{x}^{2}+{y}^{2}}$

$theta=\mathrm{arctan}2(y,x)\text{\hspace{0.17em}}radians$

## x

The x rectangular component of x + y*i*.
This input supports scalar numbers, arrays or clusters of numbers, and arrays of clusters of 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.

## y

The y rectangular component of x + y*i*.
This input supports scalar numbers, arrays or clusters of numbers, and arrays of clusters of 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. **r** has the same data type structure as **x** and **y**.

Data Type Changes on FPGA

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

## theta

The angle for the line, *r*, from the origin to the point in radians. **theta** has the same data type structure as **x** and **y**.
