The ^ symbol means exponent rather than exclusive or, and is intended to have a
higher precedence than the unary minus or the addition operator, so
that -2^8 means -(2^8) or -256.

Thus

    -2^31+1  =  -2147483647

and

     2^31-1  =   2147483647

Lawrence and I are claiming the exact same thing stated in different terms.
I'm sometimes too lazy to write the decimal constants.

No lollipop.
