ee.Number.atan
Computes the arctangent in radians of the input.
| Usage | Returns |

this: input | Number | The input value. |
Examples
print('Arctangent of -1e13', ee.Number(-1e13).atan()); // -1.570796326 (-π/2)
print('Arctangent of -1', ee.Number(-1).atan()); // -0.785398163
print('Arctangent of 0', ee.Number(0).atan()); // 0
print('Arctangent of 1', ee.Number(1).atan()); // 0.785398163
print('Arctangent of 1e13', ee.Number(1e13).atan()); // 1.570796326 (π/2)
Python setup

Python Environment page for information on the Python API and using
geemap for interactive development.
import ee
import geemap.core as geemap
# -1.570796326 (-π/2)
print('Arctangent of -1e13:', ee.Number(-1e13).atan().getInfo())
print('Arctangent of -1:', ee.Number(-1).atan().getInfo()) # -0.785398163
print('Arctangent of 0:', ee.Number(0).atan().getInfo()) # 0
print('Arctangent of 1:', ee.Number(1).atan().getInfo()) # 0.785398163
# 1.570796326 (π/2)
print('Arctangent of 1e13:', ee.Number(1e13).atan().getInfo())

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"]]
