Calculates the number of one-bits in the 64-bit two's complement binary representation of the input.
| Usage | Returns | Number.bitCount() | Number |
| Argument | Type | Details | this: input | Number | The input value. |
Examples
Code Editor (JavaScript)
print(ee.Number(0).bitCount()); // [0]
print(ee.Number(1).bitCount()); // [1]
print(ee.Number(2).bitCount()); // [1]
print(ee.Number(3).bitCount()); // [2]
print(ee.Number(0xFFFF).bitCount()); // [16]
// https://en.wikipedia.org/wiki/Two's_complement signed values.
print(ee.Number(-1).bitCount()); // [64]
print(ee.Number(-1, ee.PixelType.int8()).bitCount()); // [64]
print(ee.Number(-2).bitCount()); // [63]
Python setup

Python Environment page for information on the Python API and using
geemap for interactive development.
