ee.Number.bitwiseAnd

  • This function calculates the bitwise AND of two numbers, left and right.

  • The result is a new number where each bit is 1 only if the corresponding bits in both input numbers are 1.

  • It's useful for manipulating binary representations of numbers, like extracting specific bits or applying masks.

  • The example demonstrates how the function works with unsigned 8-bit numbers, calculating the bitwise AND of 25 and 21.

  • You can use this function in both JavaScript and Python within the Google Earth Engine environment.

 Calculates the bitwise AND of the input values.

UsageReturns
Number.bitwiseAnd(right)Number
ArgumentTypeDetails
this: leftNumberThe left-hand value.
rightNumberThe right-hand value.
