示例
代码编辑器 (JavaScript)
print('5 ** 2', ee.Number(5).pow(ee.Number(2))); // 25
print('-5 ** 2', ee.Number(-5).pow(ee.Number(2))); // 25
print('5 ** -2', ee.Number(5).pow(ee.Number(-2))); // 0.04
print('5 ** 2.2', ee.Number(5).pow(ee.Number(2.2))); // 34.493241536
print('5.2 ** 2', ee.Number(5.2).pow(ee.Number(2))); // 27.040000000
