ee.Array.bitwiseAnd

  • The Array.bitwiseAnd method calculates the bitwise AND of two input arrays on an element-wise basis.

  • This method returns a new Array containing the results of the bitwise AND operation.

  • Both the left-hand (this) and right-hand (right) arguments must be arrays.

 On an element-wise basis, calculates the bitwise AND of the input values.

UsageReturns
Array.bitwiseAnd(right)Array
ArgumentTypeDetails
this: leftArrayThe left-hand value.
rightArrayThe right-hand value.

Examples

Code Editor (JavaScript)

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

print(ee.Array(0).bitwiseAnd(ee.Array(0)));  // 0
print(ee.Array(0).bitwiseAnd(ee.Array(1)));  // 0
print(ee.Array(1).bitwiseAnd(ee.Array(0)));  // 0
print(ee.Array(1).bitwiseAnd(ee.Array(1)));  // 1
print(ee.Array(0xFF).bitwiseAnd(ee.Array(0xFFFF)));  // 255
print(ee.Array(0xFFFF).bitwiseAnd(ee.Array(0xFF)));  // 255

print(ee.Array(-1).bitwiseAnd(ee.Array(0xFF)));  // 255
print(ee.Array(-1).bitwiseAnd(ee.Array(-2)));  // -2

print(ee.Array([6, 6]).bitwiseAnd(ee.Array([1, 11])));  // [0,2]
