ee.Array.bitwiseAnd

  • Array.bitwiseAnd() calculates the bitwise AND of two input arrays element-by-element.

  • It accepts two arrays, left and right, as input and returns a new array with the results.

  • The function supports various data types and array structures, including empty arrays and multi-dimensional arrays.

  • The bitwise AND operation is performed on corresponding elements of the input arrays, aligning them by index.

  • Refer to the examples for demonstrations of the function's behavior with different input values and array configurations.

 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]
