It accepts a numerical input and returns the corresponding arctangent value as a number. The function is demonstrated with examples using inputs of -1e13, -1, 0, 1, and 1e13, showcasing the output range from -π/2 to π/2. The code examples show implementation for JavaScript and Python, where the method is called on an input number, `Number.atan()` or `ee.Number().atan()`.\n"]]
