The same strat can be applied to zeroFloorSub:

function zeroFloorSub(uint256 x, uint256 y) internal pure returns (uint256 z) {
          assembly {
              z := mul(gt(x, y), sub(x, y))
          }
}

from 399 to 361 gas

Of course!

Of course!

@AtomicAzzaz you want to do it or should I do it ?

I've already done it!
