# atan2

## Description

atan2 measures the counterclockwise angle θ, in radians, between the positive x-axis and the point (x, y).

## Input / Parameter

| Name | Description                           | Input Type | Default | Options | Required |
| ---- | ------------------------------------- | ---------- | ------- | ------- | -------- |
| x    | The x-axis value of the point (x, y). | Number     | -       | -       | Yes      |
| y    | The y-axis value of the point (x, y). | Number     | -       | -       | Yes      |

## Output

| Description                   | Output Type |
| ----------------------------- | ----------- |
| Returns the angle in radians. | Number      |

## Example

In this example, we will get the angle using `Math.atan2` function and print it in the console.

### Steps

1. Drag a `button` component into the canvas and open the `Action` tab. Select the `press` event of the button and drag the `Log.write` function to the event flow.
2. Call the function `Math.atan2` inside the `Log.write` function.
3. Enter the value to get the angle of.
