Late to the party. FWIW, the only way I can think of 0 as of a positive integer is when it is represented using fixed-width two's complement (e.g. Java's byte, short, int, and long). In that case, the sign bit for 0 is cleared, just like that of a positive integer and unlike that of a negative integer, assuming the same representation. For example, the following expression will tell you if an `int i` is non-negative, i.e. zero or positive: i >>> 31 == 0 ------------- PR Comment: https://git.openjdk.org/jdk/pull/14479#issuecomment-1624425467
