Knut Anders Hatlen commented on DERBY-5546:
-------------------------------------------
I think the suggested changes are fine. Could the underflow check be factored
out to a shared helper method?
I haven't tested, but I suspect the API comment about loss of precision in
BigDecimal.floatValue() also refers to numbers like 1.00000(...)00001 being
truncated to 1. Does/should updateBigDecimal() fail in that case too?
> ResultSet#updateBigDecimal on a REAL column does not do underflow checking
