Isb.
Kuphindwe kayishumi ngokuphindwe kayishumi, ifomula: ikhanda liphindaphindwe ngekhanda, umsila kanye nomsila, umsila uphindaphindwe ngomsila
Inhloko iyafana, futhi umsila uyahambisana (umsila wengezwa kokulingana no-10): Ifomula: Ngemuva kokufaka u-1 ekhanda, ikhanda liphindaphindwa yinhloko bese umsila wanda ngomsila.
Isiphindaphindeli sokuqala siyahambisana, kanti esinye isiphindaphindo sinezinombolo ezifanayo: ifomula: ngemuva kokungeza u-1 ekhanda, ikhanda liphindaphindwa yinhloko, futhi umsila wandiswa ngomsila.
Ikhanda liyahambisana (ikhanda lilingana no-10), nomsila uyefana. Ifomula: phindaphinda amadijithi amabili, engeza i-mantissa kumkhiqizo, futhi inombolo isetshenziswa njengomkhiqizo wangaphambili, kanti ama-mantissas amabili iphindaphindwe (okungukuthi, isikwele se-mantissa), futhi inombolo isetshenziswa njengomkhiqizo ongemuva.
