Create a numeric UDF, and edit the mask to include a trailing "-" (so negative values are accepted and displayed properly).
#,###,###.000-
This presents a warning about too many decimals / rounding, when I am clearly not exceeding three digit decimal precision. Every time I go to edit the UDF, the warning is repeated.
Is this a false warning / bug, or a real problem I should be concerned with?
