It can work for simple scenario but if you save a float with e120 and save it and you get e70
then you are in trouble.

You are not in trouble. And if you are, then you are exactlty the same as if you were using a literal parser.
You have a specification. You say that floats are written in THIS XXX text representation. Nobody cares how your floats are represented inside your Smalltalk. For JSON you write floats in a particular way, explained by the JSON specification.
Then, when you code the parser, you will need to crate an instance of Float from the string. Each dialect will know how to do that.
So, again, where is the problem?
And how the literal parser would solve it?�� because I think it will happen the same.
