$1.$ The IEEE Standard $754$ representation of a floating point number is given as:

$01001110110011010100000000000000.$ Determine the binary value represented

by this number.

$2.$ Represent the number $1\mathrm{.}01011010100$ x $2-18$ in IEEE Standard $754$ single

precision floating point binary.

$3.$ Prove your knowledge of that by converting each of the following decimal

numbers to hexadecimal by first converting the decimal to binary first, $11-10-$

$5-710$
