Fractional bits beyond the rounding point are set to zero in the result. If the exact result value cannot be represented, the saturated result value is returned. Currently, bits beyond the rounding point are always cleared, no matter whether or not the intermediate result is representable or not. ^ permalink raw reply [flat|nested] 4+ messages in thread
