You should check the math on a real calculator.
Despite what most JavaScript implementations will tell you, 2 to the 55th power is 36028797018963968, and adding one to that value is 36028797018963969. That's clearly odd.
There is no extra code between the parens. I just put them there so there wouldn't be any question as to operator precedence. I do see now that hn ate my double star, but I think you know what I mean since you told me the value that is spits out when you do the exponentiation
