>>>I use a double field with 15 decimals because I do unit conversions on the fly when the user changes the unit (droplist in another column).
>>>The DynanicInputMask Property of the column displaying the converted number depends on a mask assigned to the unit (ex:gal=999.9, lb=9999, kg=9999).
>>>The value gets truncated instead of rounded. (1.58156897 will display 1.5 instead of 1.6 for mask 999.9)
>>>My column is bound to my field ans I don't want my field value to be rounded, just "displayed" as rounded.

use my second suggestion.
