Okay -- while some of the changes here are clearly bugs, that doesn't obviate the need for a quick CSR review.

Regarding _integer_ values, 0 is conventionally neither positive nor negative; it stands alone, hence Math.signum(int):

"Returns the signum function of the specified int value. (The return value is -1 if the specified value is negative; 0 if the specified value is zero; and 1 if the specified value is positive.)"

Therefore, "non-negative" integers include zero while "positive" integers do not.
