When an overflow exception occurs and OE is set the intermediate result should be adjusted (by subtracting from the exponent) to avoid rounding to inf. The same applies to an underflow exceptionion and UE (but adding to the exponent). To do this set the fp_status.rebias_overflow when OE is set and fp_status.rebias_underflow when UE is set as the FPU will recalculate in case of a overflow/underflow if the according rebias* is set.
