BUG #: 58371 (SQLBUG_70)
BUG #: 55457 (SQLBUG_70)
SYMPTOMS
If you perform multiplication or division operations on numeric or decimal data types that have negative values, you may see unexpected results.
WORKAROUND
If the value -0 is already stored in a numeric or decimal column, and you want to make a comparison with 0 (zero), use the ABS Transact-SQL function on the column.

For example, if the value is in a column named nvalue, the WHERE clause of the query would look like this:
WHERE ABS(nvalue) = 0.0
