Persisting float number

[Hilaire Fernandes]

I have found that when persisting the number 0.1, closing the 
connection, openning it again and fetching the value I got 
0.1000000014901161

I saw that problem in a deep graph, but the problem seems repeatable 
(with squeak 3.9)

I took a look at the serialization process of Float without much 
understanding
