Code: I'm doing a saturating short arithmetic.

when {
                    a == 0.toShort() || b == 0.toShort() || (a > 0) xor (b > 0) -> a+b
                    x > 0 -> if (Short.MAX_VALUE - a < b) Short.MAX_VALUE else a + b
                    else -> if (Short.MIN_VALUE - a < b) Short.MIN_VALUE else a + b
                }.toShort()

also xor is logically equivalent to !=
