135 All four rounding modes prescribed by the IEC/IEEE Standard are implemented
136 for all operations that require rounding.  The rounding mode is selected
139 `float_round_down', or `float_round_up'.  The rounding mode is initialized
146 For extended double precision (`floatx80') only, the rounding precision
157 (`float64'), respectively.  When rounding to reduced precision, additional
158 bits in the result significand beyond the rounding point are set to zero.
183 for underflow either before or after rounding.  The choice is made by
