Answer

There are 27 different possible floating-point numbers. If the exponent is 1, there are nine possibilities, one for each possible mantissa, representing:

10 20 30 40 50 60 70 80 90

If the exponent is 0, the possible numbers are:

1 2 3 4 5 6 7 8 9

Finally, if the exponent is -1, we can have:

0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9
