It returns 0 if the input is 0, 1 if the input is positive, and -1 if the input is negative. The function operates on a single numerical input (`this: input`). Examples demonstrate its usage in both JavaScript and Python, showing the expected outputs for negative, zero, and positive inputs. It uses `ee.Number` for both environments.\n"]]
