$3)$ Show the IEEE $754$ binary representation of the number $1259\mathrm{.}125$ten $(10011101011\mathrm{.}001$two$)$ in single precision and double precision. $($Exponent is $$biased$$ to make sorting easier. In IEEE $754,$ bias of $127$ for single precision and bias $1023$ for double precision.$)$
