rightArrayThe right-hand value.

Examples

Code Editor (JavaScript)

print(ee.Array([1]).multiply(0));  // [0]
print(ee.Array([1]).multiply(1));  // [1]

print(ee.Array([1]).multiply([0]));  // [0]
print(ee.Array([1]).multiply([1]));  // [1]

// [-1,8,-2,4.8]
print(ee.Array([1, -2, 2, 4]).multiply([-1, -4, -1, 1.2]));

// [-1,2,-2,-3]
print(ee.Array([1, -2, 2, 3]).multiply(-1));

var empty = ee.Array([], ee.PixelType.int8());
print(empty.multiply(empty));  // []
