No Need to send the MSB bit of mantissa if Exponent is > 0
v= (-1) Power S X T, for E=0, i.e. |v|< 2powert,
v= (-1) power S\0xb7(2 power t+T)\0xb72 power (E-1), for
E>0, i.e. |v|\0x2265 2 power t
1 -> send the MSB bit of mantissa always
v= (-1) power S\0xb7T\0xb72 power E, for all values of E.
S is Sign bit, T is Mantissa, E is exponent
