The exponent is represented using excessn and the significand is represented using signed binary, which allows the significand to be conveniently split into a sign bit and an unsigned magnitude that. This is also a bad thing, because distinguishing between signed and unsigned is our responsibility the distinction is very important when detecting an overflow after addition or subtraction correct approach to detect the overflow is to consider two. The other major way of storing negative signed numbers is called ones complement. It allows the representation of numbers in the range 2n to 2n1, and has the major advantage of only having one encoding for 0.
