1.1111111 = 10.0000000 - 0.0000001          2^1 - 2^-7 

(2^1 - 2^-7)*2^31 = 2^32-2^24

B. Normalized minimum

1 - 31 = -30 unbiased exponent

1.0000000 x 2^-30

C. Denormalized minimum

0  000000 0000001

1 - 31 = -30 unbiased exponent.  Because an all zero exponent is a flag and
not an actual value, assume there is a 1. 

0.0000007 x 2^-30 = 1.0 * 2^-7 * 2^-30 = 1 * 2^-37
