The mantissa is stored as Integer. I think that is the only way to keep 
all digits. But with that representation it is certainly not sensible to 
normalize to the most significant digit. A reasonable normalization might 
be to divide the mantissa by a power of 10 such that the mantissa is not a 
multiple of 10.
