Abstract

For reduksjon av avrundingsfeil bruker man en første og en andre ikke heltallig inngangsstørrelse (260, 262) og kombinerer disse (268), for eksempel ved summering, i ikke heltallig tilstand slik at man kommer frem til en ikke heltallig resulterende utgangsstørrelse som deretter avrundes og tilføyes (269) en tredje inngangsstørrelse. Følgelig kan avrundingsfeilen reduseres i et grensesnitt mellom to rotasjoner som er delt opp i løftetrinn eller mellom en første rotasjon som er delt opp i løftetrinn og et andre løftetrinn tilhørende en etterfølgende flerdimensjonal løftesekvens.
