Question

Please help me with A+B, A-B, A*B and A/B

A= 1 0101 101
B = 0 0011 001
Binary to Decimal Conversion
A+B
Minifloat format: 1 0101 011
w
A-B
Minifloat format: 1 0101 111
A*B
Minifloat format: 1 0001 111
Note with this question, if the exponent on A or B was 2 lower (say -4, -4) then the resulting exponent
would be -8, add the bias.. and you can't represent -1 as an exponent so the problem wouldn't have a
valid solution.
