Richtig

Jetzt habe ich dieses Beispiel von der Fernuni Hagen immer wieder Gerechnet. Ich sollte mir jetzt selber ein Programm generieren

Der witz ist - dass ich bei der Nachkommastelle keine seltsame Zahl haben will - also ich moechte kein 0.712831233333 haben, weil, dann kriege ich probleme mit der Rundung

Und deswegen muss ich mir jetzt ein sinngemaesses Programm schreiben

Die Frage ist wie

wenn ich zum Beispiel

1/4 geht 1/8 geht 1/16 geht

Das koennte man so machen.

das man einfach

n als Zufallszahl nimmt und so oft zwei miteinander multipliziert. n sollte nicht groesser als 8 sein

Und dann teilt man 1 dadurch

Ok und fuer das vor dem Komma, nimmt einfach eine Zahl zwischen

1 und 21̂5

Das funktioniert schon mal ganz gut

Rechne die Zahl in IEEE-754 um 30148.031250
Rechne die Zahl in IEEE-754 um 23287.031250
Rechne die Zahl in IEEE-754 um 5402.125000
Rechne die Zahl in IEEE-754 um 23607.007812

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main (void) {
    time_t t;
    int n;
    float f1 = 1;
    float f2;

    srand ((unsigned )time (\&amp;t));

    f2 = (float) (rand () % (8192 * 4));

    n = (rand () % 8) + 2;

    while (n > 0) {
        f1 = f1 / 2;
        n--;
    }

    f2 = f2 + f1;

    printf ("Rechne die Zahl in IEEE-754 um %fn", f2);

return 0;
}

Jetzt mache die Schriftlichen Aufgaben.

1.) Rechne die Zahl in binaer Darstellung  in eine Dezimale Darstellung um
1111111010110111b 65207d
2.) Rechne die Zahl in dezimal darstellung in eine Binaerdarstellung um
21514 0101010000001010
3.) Addiere die drei Zahlen schriftlich
            62758
+            8634
+           27769
-----------------
            99161
4.) Subtrahiere die letzten drei Zahlen schriftlich von der ersten schriftlich
             6534
-            1457
-            5547
-             741
-----------------
            -1211
5.) Rechne die Zahl ins zweier komplement um, mit 8 Bit - und subtrahiere diese zahl von der ersten und rechne das Ergebnis nach dezimal
-103 -24 = -127
10011001 11101000 = 10000001
6.) Multipliziere die zwei Zahlen schriftlich
56885*340 = 19340900
7.) Dividiere die zwei Zahlen schriftlich
38673/15591 = 2
8.) Errechne x Logarithmisch mit dem Taschenrechner
64764\^x = 1739002694
