This is just the way internal floating point comparison 
usually works:

First both values are normalized to the binary 0.---
then the resulting exponents are compared, 
then only if these are equal the matissae are compared.

==============

If you want to do this in [base 10] integer arythmetic,
the nice thing is that you can compare the above "content",
left-to-right only as long as the characters are the same,
promissing enormous performance gain.
