# Atan2

> **Note:** **What is it about?**
>
> This page documents the **Atan2 node** of the Scene Nodes system in **Cinema 4D**. It computes the angle between the positive X-axis and a 2D direction vector — the sign-aware full-circle angle for radial logic.

This calculation results in the output of the angle between the positive X axis of a 2-dimensional coordinate system and the directional vector for Position X, Y.
