in Single precision format , we divide the number in the following way
MSB =sign bit
next 8 bit= Exponent
Rest 23 bit =mantissa
here sign=1
exponent=10000100=132
Now we know , fo biasing we have to subtract 127 from the Exponent
real exponent=132-127(as it is in single precision)=5
mantissa=111100000 ... 0
so the number is (1.M)XE(real exponent)=1.1111000...0 X 25 =111110
which is 62
now sign bit=1 , so it is negative number
answer= -62
correct me, if i am wrong
