„Procentberegning

z[ 2nd ] [ % ] dividerer tallet i displayet med 100. Du kan bruge denne tastsekvens til at beregne procenter, tillæg, rabatter og procentforhold. Se eksempel 20~21.

„Fortløbende beregninger

zLommeregneren giver dig mulighed for at gentage den senest

udførte handling ved at trykke på tasten [ ], så der foretages yderligere beregninger. Se eksempel 22.

zOgså hvis en beregning afsluttes med tasten [ ], kan det opnåede resultat anvendes til videre beregninger. Se eksempel 23.

„Svarfunktion

zSvarfunktionen gemmer det senest beregnede resultat. Det bevares også, efter at der slukkes for strømmen. Når der indtastes en numerisk værdi eller et numerisk udtryk, og der

derefter trykkes på [ ], gemmes resultatet af denne funktion. Se eksempel 24.

(Bemærk) : Selv hvis afviklingen af en beregning fører til en fejl, opbevarer svarhukommelsen dens aktuelle værdi.

„Logaritmer og antilogaritmer

zLommeregneren kan beregne almindelige og naturlige logaritmer

og antilogaritmer ved hjælp af [ log ], [ ln ], [ 2nd ] [ 10 x ] og [ 2nd ] [ e x ]. Se eksempel 25~27.

„Brøkregning

Brøkværdier vises som følger :

5 / 12

56 ∪ 5 /12

5

Displayet viser 12

5

Displayet viser 56 12

zHvis du vil indtaste et blandet tal, skal du indtaste heltalsdelen ved at trykke på [ a b/c ], indtaste tælleren ved at trykke på [ a b/c ] og indtaste nævneren. Hvis du vil indtaste en uægte brøk, skal du indtaste tælleren, trykke på [ a b/c ] og indtaste nævneren. Se eksempel 28.

zHvis et tal kan reduceres under en brøkberegning, reduceres det til den mindste fællesnævner, når der trykkes på en funktionskommandotast ( [ + ], [ – ], [ x ] eller [ ] ) eller på tasten

[ ]. Hvis du trykker på [ 2nd ] [ a b/c d/e ], konverteres den viste værdi til den uægte brøk og omvendt. Se eksempel 29.

zHvis du vil konvertere mellem et decimal- og et brøkresultat, skal

du trykke på [ 2nd ] [ FD ] og [ ]. Se eksempel 30.

Da – 12
