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)
