In all seriousness tho', where do you ever provide a two bit number? $n = 2; The above is a number, it's not implicitly a two bit number... I mean, if I do: $n = 2; $n += 2; What do I get then? $n == 0? That's what *should* happen if $n was indeed two bits. It would overflow and wrap around. Your number in $n is in fact represented by whatever the variable type is. In this case it's a 32 bit integer number.
