In GUI we do not know what precision user mean (or we have to store it), so it 
is no useful information.

In file precision mean storage precision and is known. Anyway, fixed format is 
preferable in machine read data. Note, if you speak about human readability, 
not storage efficiency, such precision would be precious information. If you're 
about efficiency, you would prefer binary file or BASE64 at least.

Also as I noted above %g may switch to exponent format (AFAIR it is not 
specified by standard -- when it happen), which could be undesirable.
