The question asks, what is the largest unsigned int that can be represented between two floats? and what does it round to?

The answer is that it falls between 2^(32) and 2^(32)-2^(8) and half way between those two floats is 2^(32)-2^(7) which rounds to 2^32 away from odd..

What i dont get is, where did they get 2^8 from???

can anyone help?
