Rnd() of greater value as Long

 

Jörg

gives it a Possibility a Zufallszahl a area ulterior the Longgrenze To detect.

If I
Var n! = 4^16
Print Rnd(n!)
use, comes only 0 out. Gibts there what by Api or so?

ex in String and then to that Float or mean You something other?

string s

whileloop 12 {s=s+str$(rnd(10))}

float f=val(s)/pre>

Yes the Have I already, but the numbers can not higher as 4^16 his.

strange - Why diving because Franks Posting only here on:
[...] 

The Solutions having unfortunately any whom disadvantage, that tappt im dunkeln no 4^16 To 1 probability image, separate any kombinatorischen.
Z. B. is with one real Rnd() with large numbers The probability 1:1, that the number larger or small is, as 4^16 : 2.
In iFs example is the probability but already 10:1, that the number 10-stellig is (4^16 is incidentally 10- and not 12-stellig).
Ähnliches counts for Franks (verschwundenes) example.
has someone ne idea, How I the concern could? or could the even in Profan be installed? is probably ne solid verdrahtete Delphilösung, or?

Declare Zufall_Save!, Zufall_Obergrenze!

Proc Zufall

    Declare x1!,x2!
    x1! = (Zufall_Save! * 65539)
    x2! = Round((x1! / Zufall_Obergrenze! - 0.5),0) * Zufall_Obergrenze!

    Return Zufall_Save!

EndProc

Declare x!

Zufall_Save! = 7

repeat

    cls
    print obergrenze.:, format$(#,0,Zufall_Obergrenze!),    WaitKey: 13 = Enter = weiter, sonst Ende
    print save.......:, format$(#,0,Zufall_Save!)
    print
    print die Zufallszahl;tab(45);Kontrollwert (Max - Zufall)

    whileloop 20

        x! = zufall()
        print x=,format$(#,0,Round(x!-0.5,0));tab(45);format$(#,0,Round(Zufall_Obergrenze! - x! - 0.5,0))

    endwhile

    waitkey

until %key <> 13

end

About The distribution can I but nothing say - be no Mathematiker

Perhaps because I my Posting again deleted having? I found The method later badly, because the detour a area Yes none necessary is is.

Why take You do not simply chance! = rnd(4^8) * rnd(4^8)?
the Result is always >= 0 and < 4^16.

Pardon:
an better (korrekte) distribution the Zufallszahlen get one naturally with:
CompileMarkSeparation
Zufall! = 4^(rnd(8)+1) * rnd(4^8)

... and ex the next XProfan-Version there too whom Sonderfall Rnd(), the bislang you don't say so was. the Result is then one Flloatwert >= 0 and < 1. Dann löst Du Dein Problem einfach mit:

Very beautiful! any combined values are namely somehow gemauschelt and correspond to not the tatsächlichen probability.
leaves itself here very slight understand:
