Question 14. When adding two floating point numbers, the exponents are first
made the same by shifting one of the fractions (if necessary). The fractions
are then added, and the result normalized (if not already so).
Let 0x3EE00000 and 0x3D800000 be two floating point numbers in standard
IEEE format. Add the two numbers, and show the normalized result in
hexadecimal.
