#  Math: Calculate arctangent2 in radians

This action is in beta and the function or availability may change unexpectedly.

Use this action to calculate and convert the arctangent2 of cartesian coordinates (x,y) to polar notation in radians. Arctangent2 is typically stylized as `atan2(y,x)`. It is used instead of arctan(y/x) when calculating an arctangent where both signs of the arctan2 arguments are used to determine the quadrant of the result.

## How to configure this action When configuring this action, reference a Integer or decimal in the X field configuration, and enter an Integer or decimal or reference a field in the Y field configuration. How do I reference a field?

For more advanced math, use Javascript with the Field: Field Formulas action.

## Fields for this action • #### X • The cartesian coordinate X to use in the calculation. This is the second argument when calculating atan(y,x).
• #### Y • The cartesian coordinate Y to use in the calculation. This is the first argument when calculating atan(y,x).
• #### Output field prefix • To help keep output fields organized, choose an output field prefix to add to the beginning of each output field name as this action may output more than one field.

## What will this output? This action may generate multiple fields. To help keep output fields organized, the prefix above will be added to the beginning of each of the output field names, separated by two dashes. Each field will result as:`{{output-field-prefix--output-field}}`.

### Output fields for this action • #### Result • The result of the operation. The output is a decimal type field.

##### The results field is empty Math actions require integer or decimal values. If you enter an incompatible value for the input, the output may be blank. For example, attempting to perform an operation on the value `Marine Biologist` will always return an empty field.
