It is possible to input float values into a custom field of type Number with any precision.
A maximum precision of 6 digits after decimal point is stored into the database.
I can recover the complete value if I ask for the XML view of the issue.
Any other view (Issue page, Navigation page, Word, Excel) show only a maximum of 3 digits
to the right of the decimal point. The number is rounded up.

I have a big problem with this because I used a custom Number Field to store a revision number
containing a dot. I would like to change this number to a text field, but this means I'll lost all values
stored in the database, because I see no other way than deleting the field and creating it anew.
When I noticed that every number is rounded up to 3 digits after the decimal point it was too late.
3 digits is quite a little precision! Why this limit? Is there any workaround?
