Int64 5.46.0

final class · pocketmine\world\generator\vanilla\math\Int64 · source

Wrapping 64-bit integer arithmetic with Java long semantics. PHP turns overflowing int + and * into floats, so these helpers work on 16/32-bit limbs instead. They are only used when seeding random sources, never in per-block loops.
