And then, we convert the 0.1875to 1.5×2−3.After that, we convert the 0.5 to F=100,0000,0000,0000,0000,0000 fraction part and the Exponent part for this case is 127−3=12410=0111,11002.So in conclusion:S=1E=0111,1100F=100,0000,0000,0000,0000,0000Answer b:The first step, we find that this floating point is negative, so S=0. And then, we convert the 0.46875to 1.875×2−2. After that, we convert the 0.875 to F=110,0000,0000,0000,0000 and the Exponent part for this case is 127−2=12510=0111,11012.So in conclusion:S=0E=0111,1101F=110,0000,0000,0000,0000Answer a: For the first step, we convert the Hexadecimal to binary which is 0011,1111,0100,0000,0000,0000,0000,0000. After this, we separate three section.0|011,1111,0|100,0000,0000,0000,0000,0000. We can indicate that this is the positive decimal number, since the first sign section number is 0. For the exponent section we have 0111,1110 which stand for decimal 12610. So this is the power of 126−127=−1. Since the actual fraction is1.100,0000,0000,0000,0000,0000=1+1×2−1=1.510.So the actual decimal is 1.5×2−1=0.75Answer B:For the first step, we convert the Hexadecimal to binary which is 1011,1110,0000,0000,0000,0000,0000,0000. After this, we separate three section.1|011,1110,0|000,0000,0000,0000,0000,0000. We can indicate that this is a negative decimal number, since the first sign section number is 1. For the exponent section we have 0111,1100 which stand for decimal 12410. So this is the power of 124−127=-3. Since the actual fraction is1.000,0000,0000,0000,0000,0000=12=110. So the actual decimal is −1×2−3=−0.25.1.
