Like AND, OR, and XOR.
Infact, just AND, OR, and XOR.
(And not just in the conditions, in the actual gene itself too, darnit.)
(For those who don't understand how they work, you hafta look at the number in binary to fully understand.
AND checks each bit of two values, and unless both are 1, the result will be 0.
I.E.
10100101 AND
00101101 equals
00100101.
OR checks each bit of the two values, but unlike AND, only one of the two bits have to be 1 for the result to be 1.
I.E.
10100101 OR
00101101 equals
10101101.
And XOR checks each bit of two values, but unlike AND and OR, it only results in 1 if ONE (and no more then one) of the bits is 1. (They basically have to be different. The bits, that is.)
I.E.
10100101 XOR
00101101 equals
10001000.)
