NUMBER SYSTEM FLOATING POINT

Question

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 is -128 and adding 127 will  make it -1, which is certainly negative. So how do we get postitive exponent by biassing in this case??.

It sounds confusing to me. Plz resolve my confusion.

Comments

what you said sounds completely logical. I also learned that that only. But from internet and everywhere got confused.

if they are using 127 as bias means their maximum negative no possible cant be more than -127..must be some modifications with range has been done..whatever it is we have to add positive to max negative no possible to make every no as 0 or +ve

Thanx @ Sudsho :)
