[Gvsig_english] Precision field

[Claudio]

Dear all,
the problem is about the "limit" of the precision in the double field with a dbf...
I saw that the precision of a double field is limited to 6 and it is a problem, sometimes. Working with some hydrological measures, I would to save the full value (10E-10 for example), but it is possible only with a postgresql DB link. 
There is some solution to this problem? May be the gvsig dbf driver?

Thanks :-)

Claudio
