Hi,
personally I would store uF or nF as double precision values. Then, use the
new OnGetDisplayText etc. properties to convert the stuff just-in-time. Let
me know if I should elaborate.

These events for just-in-time conversion are available (at least) in
TIB_Grid, TIB_Edit, and TIB_LookupCombo.

Cheers,
Tobias
