Creates a complex number from two values in polar notation.

Given z in rectangular form z = a + b*i*, this node converts the polar components according to the following equation:

## r

The distance from the origin to the point, *z*.
This input supports scalar numbers and fixed-size 1-dimensional arrays 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.

## theta

The angle for the line, *r*, from the origin to the point, *z*, in radians.
This input supports scalar numbers and fixed-size 1-dimensional arrays 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.

## z

The complex number.
**z** has the same data type as **r** and **theta**, with complex representation instead of scalar.
