When two 8bit numbers $A_{7}...A_{0}$ and $B_{7}...B_{0}$ in 2's complement representation (with $A_{0}$ and $B_{0}$ as the least significant bits) are added using a ripplecarry adder, the sum bits obtained are $S_{7}...S_{0}$ and the carry bits are $C_{7}...C_{0}$. An overflow is ... $\left ( A_{0}.B_{0}.\bar{S_{0}}+\bar{A_{0}}.\bar{B_{0}}.S_{0} \right )$ is 1

NUMBER SYSTEM FLOATING POINT
IN FLOATING POINT REPRESENTATION WE KNOW THAT BIAS ADDED IS THE MAXIMUM NUMBER WHICH CAN BE REPRESENTED IN 2S COMPLEMENT. Suppose exponent is represented using 8 bits, so bias added= (2^7)1=127. But the max negative number representable with 8 bits ... So how do we get postitive exponent by biassing in this case??. It sounds confusing to me. Plz resolve my confusion.

Consider the following floatingpoint format. Mantissa is a pure fraction in signmagnitude form. The normalized representation for the above format is specified as follows. The mantissa has an implicit $1$ preceding the binary (radix) point. Assume that only $0's$ are padded in while shifting a field ... the above number $(0.239 \times 2^{13})$ is: $0A\;20$ $11\;34$ $49\;D0$ $4A\;E8$
