The way to get around this is to fix the bug in your
expression that gives you the numeric overflow exception.

Although using the fixed format arithmetic ops with
decimal numeric operands will (by default) truncate
results, for numeric expressions, the behavior is much
more complicated and truncation (if allowed) would more
often yield results that you did not expect.

BTW, moving *HIVAL into a field is NOT the same as
truncating a result.  Also, I hope that when you put
*HIVAL into the field, you treat that as some special
value and not as the actual result of the computation.
