ee.Number.bitwiseNot

  • Number.bitwiseNot() calculates the bitwise NOT of a number, essentially flipping each bit in the binary representation of the input.

  • The result is interpreted as a signed integer using the smallest data type that can accommodate the input value.

  • For example, the bitwise NOT of 25 (binary 00011001) is -26 (binary 11100110 in signed 8-bit representation).

 Calculates the bitwise NOT of the input, in the smallest signed integer type that can hold the input.

UsageReturns
Number.bitwiseNot()Number
ArgumentTypeDetails
this: inputNumberThe input value.

 * (binary interpreted using smallest signed integer type containing the input).
