We’re trying to put -11/32 into a floating point binary number with 8 bits for the mantissa and exponent (each).
We get 10101000 11111111
mantissa: 1.0101
exponent: -1 (dec)
but our textbook gets 10100000 11111111
which we decode back to get -3/8
mantissa: 1.01
exp: -1 (dec)
Can anyone confirm why these are different / who is right?
(we are going mad)
Thanks!
Edit: I should say, we’re using two’s complement for both the mantissa and exponent parts.
